involved in particle-bubble interactions. The collision efficiency (EC) is used as an indicator to assess the extent of these interactions. In this work, the bubble surface is assumed mobile with potential flow conditions dominating the particle-bubble collision efficiency. The collision probability has been determined by Schulze and Generalized Sutherland Equation (GSE) models in the particle size range of 1–100 μm. Bubble diameters of 0.08, 0.12, and 0.15 cm and bubble velocities of 10, 20 and 30 cm/s were selected to study the flotation of chalcopyrite. The results reveal that the collision efficiency of ultra-fine particles (1–10 μm) is generally improved with bubbles of finer sizes, e.g. db = 0.08 cm compared to those of larger sizes, i.e. db = 0.12 and db = 0.15 cm. Also, in the same particle size range, EC decreases with increasing the bubble velocity. The best agreement between Schulze and GSE models for ultra-fine particles at all bubble sizes is achieved at the bubble velocity of 30 cm/s. The maximum EC of chalcopyrite (0.12) using the GSE model is found to occur for coarser particles of 70–100 μm in size at bubble conditions of vb = 30 cm/s and db = 0.12 cm. Results reveal that for a given bubble diameter increasing the bubble velocity from 10 to 30 cm/s makes the inertial force more effective on finer particles. A detailed interpretation of the effect of bubble diameter and its velocity on particle-bubble interaction of chalcopyrite is discussed from a theoretical point of view.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="78813275"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="78813275"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 78813275; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=78813275]").text(description); $(".js-view-count[data-work-id=78813275]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 78813275; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='78813275']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 78813275, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=78813275]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":78813275,"title":"Effect of bubble size and velocity on collision efficiency in chalcopyrite flotation A Physicochemical and engineering aspects","translated_title":"","metadata":{"abstract":"In flotation processes, bubble diameter (db), bubble velocity (vb), and turbulence are the key factors involved in particle-bubble interactions.

A detailed interpretation of the effect of bubble diameter and its velocity on particle-bubble interaction of chalcopyrite is discussed from a theoretical point of view.","owner":{"id":1308754,"first_name":"Behzad","middle_initials":null,"last_name":"Vaziri Hassas","page_name":"BehzadVaziriHassas","domain_name":"pennstate","created_at":"2012-03-16T05:53:50.316-07:00","display_name":"Behzad Vaziri Hassas","url":"https://pennstate.academia.edu/BehzadVaziriHassas"},"attachments":[],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":3746,"name":"Colloids and Surfaces","url":"https://www.academia.edu/Documents/in/Colloids_and_Surfaces"},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences"},{"id":152114,"name":"Bubble","url":"https://www.academia.edu/Documents/in/Bubble"},{"id":238108,"name":"Chalcopyrite","url":"https://www.academia.edu/Documents/in/Chalcopyrite"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES"}],"urls":[{"id":20345483,"url":"https://pubag.nal.usda.gov/catalog/5529472"}]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="78813271"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/78813271/Effect_of_various_ligands_on_the_selective_precipitation_of_critical_and_rare_earth_elements_from_acid_mine_drainage"><img alt="Research paper thumbnail of Effect of various ligands on the selective precipitation of critical and rare earth elements from acid mine drainage" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/78813271/Effect_of_various_ligands_on_the_selective_precipitation_of_critical_and_rare_earth_elements_from_acid_mine_drainage">Effect of various ligands on the selective precipitation of critical and rare earth elements from acid mine drainage</a></div><div class="wp-workCard_item"><span>Chemosphere</span><span>, 2021</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Acid mine drainage (AMD) has been of environmental concern for decades but recently found to be a...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Acid mine drainage (AMD) has been of environmental concern for decades but recently found to be a viable source of critical elements including rare earth elements (REEs).

The precipitation behavior of the REEs and other cations during the AMD neutralization process depends strongly on the solution chemistry, available ligands, and concentration of elements. Several chemicals were used to study the effect of various ions/ligands (i.e., OH-, SO42-, NH4+, CO32-, and PO43-) on precipitation behavior of REEs and other elements from AMD as a function of pH. It was found that only up to 70% of total REEs can be recovered using NaOH at circumneutral pH. (NH4)OH suppressed the precipitation of REEs up to pH 8. The presence of phosphate and carbonate ions in the solution increased the precipitation yield of REEs at lower pH values. Both Na2HPO4 and Na2CO3 were found to increase the precipitation of REEs at pH below 7, as over 85% of REEs were recovered. Calculated saturation indices and speciation diagrams for selected REEs confirmed the experimental data. Considering the elemental recovery values, environmental effects, as well as chemical consumption and cost, a two-step AMD treatment process using Na2CO3 was formulated.

Finer the particles, the higher the role of their surface on their behavior and properties. The importance of particle morphology becomes even clearer when particle-particle and particle-bubble interactions are considered. In this study, the effect of particle shape &quot;roundness&quot; on the surface wettability and flotation response was investigated upon producing fine particles with the &quot;abrasion blasting&quot; method. In order to provide a fundamental perspective, adsorption measurements were also carried out along with the flotation experiments under the same conditions. In addition to these, zeta potential measurements were also carried out with both spherical and blasted particles as a function of collector concentration. The results suggested that the roundness of particles decreased up to a certain nozzle pressure value, which was followed by higher adsorption degrees and consequently higher flotation recoveries. Additionally, settling rate tests were also performed with very fine material to show the effect of particle morphology on particle-particle interactions. The results showed that while lower settling rate values were obtained for spherical ones, higher values were obtained in the case of the ground and blasted samples in the presence of DI water. It was concluded from this study that the &quot;Abrasive blasting method&quot; could be an effective alternative for tuning the surface morphology of particles and their wettability, which in turn can affect the particleparticle interactions in the system.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="0220dddaeb927b02f058c682ce0da5fd" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{&quot;attachment_id&quot;:85725568,&quot;asset_id&quot;:78813265,&quot;asset_type&quot;:&quot;Work&quot;,&quot;button_location&quot;:&quot;profile&quot;}" href="https://www.academia.edu/attachments/85725568/download_file?st=MTczMzkzMTU2Niw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="78813265"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="78813265"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 78813265; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=78813265]").text(description); $(".js-view-count[data-work-id=78813265]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 78813265; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='78813265']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 78813265, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "0220dddaeb927b02f058c682ce0da5fd" } } $('.js-work-strip[data-work-id=78813265]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":78813265,"title":"Morphological changes of glass bead particles upon an abrasive blasting as characterized by settling and flotation experiments","translated_title":"","metadata":{"publisher":"Politechnika Wroclawska Oficyna Wydawnicza","grobid_abstract":"The recent developments in mineral processing led researchers to look for alternative methods and propose new mechanisms for enhancing the efficiency of relatively costly processes (e.g., flotation, aggregation), where especially dealing with fine particles.

Especially in exterior applications, the hydrophobic characteristic of the paints lead to protection against air humidity; moreover, some other properties such as fire retardancy and antibacterial effect of the paints may be required based on its utilization area. Mineral additives in paint constitute anywhere from 20 to 50% of the paint formulation. Due to such high proportion of mineral constituents in the paint system, the required properties of paints can be achieved by properly selecting minerals as fillers.

This fact becomes an important industrial challenge in lignite cleaning. The presence of micropores and relatively low hydrophobic nature of lignitic coal lead to trapping of large quantities of water in the coal matrix especially in fine sizes. Since lignites are used as a common fuel in power stations, they need to be dried to a certain moisture level before feeding to the combustion chamber. Dump feeding in power plants cause inevitable loss of efficiency and may be deleterious for combustion sections. It is thus generally wise to dewater coal as much as possible by physical means before it is dried. However, further dewatering cost in some cases may be prohibitive particularly for fine and hydrophilic particles. In this study, various type and amount of surfactants have been tested to increase the efficiency of coal dewatering. As the hydrophobic characteristic of coals varies and increases with increasing the coal rank, dewatering of bituminous and anthracite type coals can be accomplished using low HLB surfactants (Oily), however, these surfactants are not efficient in the case of low rank coals like lignites and brown coals. A special set-up has been designed to study the effect of high HLB surfactants on dewatering of ultrafine lignite particles. It is shown that, while surfactants with lower HLB number and oily characteristics are the most convenient dewatering reagents for slightly hydrophobic surfaces such as hard coals, surfactants with higher HLB values especially those with HLB of around 10 are the most efficient reagents for dewatering of ultrafine lignite and lower rank coals. The governing mechanisms are discussed in the light of hydrophilicity index and modification of physicochemical conditions.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="78813237"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="78813237"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 78813237; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=78813237]").text(description); $(".js-view-count[data-work-id=78813237]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 78813237; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='78813237']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 78813237, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=78813237]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":78813237,"title":"Ultrafine coal dewatering: Relationship between hydrophilic lipophilic balance (HLB) of surfactants and coal rank","translated_title":"","metadata":{"abstract":"ABSTRACT Dewatering process is one of the most costly steps in mineral processing and coal washing plants.

Recovery of these elements while treating AMD for environmental compliance improves the sustainability of the treatment process. The precipitation behavior of the REEs and other cations during the AMD neutralization process depends strongly on the solution chemistry, available ligands, and concentration of elements. Several chemicals were used to study the effect of various ions/ligands (i.e., OH-, SO42-, NH4+, CO32-, and PO43-) on precipitation behavior of REEs and other elements from AMD as a function of pH. It was found that only up to 70% of total REEs can be recovered using NaOH at circumneutral pH. (NH4)OH suppressed the precipitation of REEs up to pH 8. The presence of phosphate and carbonate ions in the solution increased the precipitation yield of REEs at lower pH values. Both Na2HPO4 and Na2CO3 were found to increase the precipitation of REEs at pH below 7, as over 85% of REEs were recovered.

Finer the particles, the higher the role of their surface on their behavior and properties. The importance of particle morphology becomes even clearer when particle-particle and particle-bubble interactions are considered. In this study, the effect of particle shape &quot;roundness&quot; on the surface wettability and flotation response was investigated upon producing fine particles with the &quot;abrasion blasting&quot; method. In order to provide a fundamental perspective, adsorption measurements were also carried out along with the flotation experiments under the same conditions. In addition to these, zeta potential measurements were also carried out with both spherical and blasted particles as a function of collector concentration. The results suggested that the roundness of particles decreased up to a certain nozzle pressure value, which was followed by higher adsorption degrees and consequently higher flotation recoveries. Additionally, settling rate tests were also performed with very fine material to show the effect of particle morphology on particle-particle interactions. The results showed that while lower settling rate values were obtained for spherical ones, higher values were obtained in the case of the ground and blasted samples in the presence of DI water. It was concluded from this study that the &quot;Abrasive blasting method&quot; could be an effective alternative for tuning the surface morphology of particles and their wettability, which in turn can affect the particleparticle interactions in the system.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="0220dddaeb927b02f058c682ce0da5fd" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{&quot;attachment_id&quot;:85725568,&quot;asset_id&quot;:78813265,&quot;asset_type&quot;:&quot;Work&quot;,&quot;button_location&quot;:&quot;profile&quot;}" href="https://www.academia.edu/attachments/85725568/download_file?st=MTczMzkzMTU2Niw4LjIyMi4yMDguMTQ2&st=MTczMzkzMTU2Niw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="78813265"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="78813265"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 78813265; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=78813265]").text(description); $(".js-view-count[data-work-id=78813265]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 78813265; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='78813265']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 78813265, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "0220dddaeb927b02f058c682ce0da5fd" } } $('.js-work-strip[data-work-id=78813265]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":78813265,"title":"Morphological changes of glass bead particles upon an abrasive blasting as characterized by settling and flotation experiments","translated_title":"","metadata":{"publisher":"Politechnika Wroclawska Oficyna Wydawnicza","grobid_abstract":"The recent developments in mineral processing led researchers to look for alternative methods and propose new mechanisms for enhancing the efficiency of relatively costly processes (e.g., flotation, aggregation), where especially dealing with fine particles.

Finer the particles, the higher the role of their surface on their behavior and properties. The importance of particle morphology becomes even clearer when particle-particle and particle-bubble interactions are considered. In this study, the effect of particle shape \"roundness\" on the surface wettability and flotation response was investigated upon producing fine particles with the \"abrasion blasting\" method. In order to provide a fundamental perspective, adsorption measurements were also carried out along with the flotation experiments under the same conditions. In addition to these, zeta potential measurements were also carried out with both spherical and blasted particles as a function of collector concentration. The results suggested that the roundness of particles decreased up to a certain nozzle pressure value, which was followed by higher adsorption degrees and consequently higher flotation recoveries.

Paints produced using colemanite were subjected to both wet and dry paint analysis and found that this mineral has favorable effect on opacity and viscosity of the system. Furthermore; colemanite has a remarkable effect on retardin...","owner":{"id":1308754,"first_name":"Behzad","middle_initials":null,"last_name":"Vaziri Hassas","page_name":"BehzadVaziriHassas","domain_name":"pennstate","created_at":"2012-03-16T05:53:50.316-07:00","display_name":"Behzad Vaziri Hassas","url":"https://pennstate.academia.edu/BehzadVaziriHassas"},"attachments":[],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="78813251"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/78813251/Interaction_Between_TiO2_and_Calcite_Calcined_Kaolin_Mixture_During_Grinding_of_Pigment_in_Water_Based_Paints"><img alt="Research paper thumbnail of Interaction Between TiO2 and Calcite-Calcined Kaolin Mixture During Grinding of Pigment in Water Based Paints" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" rel="nofollow" href="https://www.academia.edu/78813251/Interaction_Between_TiO2_and_Calcite_Calcined_Kaolin_Mixture_During_Grinding_of_Pigment_in_Water_Based_Paints">Interaction Between TiO2 and Calcite-Calcined Kaolin Mixture During Grinding of Pigment in Water Based Paints</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Water based paint formulations consist of some industrial minerals with quantities varying from 2...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Water based paint formulations consist of some industrial minerals with quantities varying from 20 to 50 %.

This fact becomes an important industrial challenge in lignite cleaning. The presence of micropores and relatively low hydrophobic nature of lignitic coal lead to trapping of large quantities of water in the coal matrix especially in fine sizes. Since lignites are used as a common fuel in power stations, they need to be dried to a certain moisture level before feeding to the combustion chamber. Dump feeding in power plants cause inevitable loss of efficiency and may be deleterious for combustion sections. It is thus generally wise to dewater coal as much as possible by physical means before it is dried. However, further dewatering cost in some cases may be prohibitive particularly for fine and hydrophilic particles. In this study, various type and amount of surfactants have been tested to increase the efficiency of coal dewatering. As the hydrophobic characteristic of coals varies and increases with increasing the coal rank, dewatering of bituminous and anthracite type coals can be accomplished using low HLB surfactants (Oily), however, these surfactants are not efficient in the case of low rank coals like lignites and brown coals. A special set-up has been designed to study the effect of high HLB surfactants on dewatering of ultrafine lignite particles. It is shown that, while surfactants with lower HLB number and oily characteristics are the most convenient dewatering reagents for slightly hydrophobic surfaces such as hard coals, surfactants with higher HLB values especially those with HLB of around 10 are the most efficient reagents for dewatering of ultrafine lignite and lower rank coals. The governing mechanisms are discussed in the light of hydrophilicity index and modification of physicochemical conditions.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="78813237"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="78813237"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 78813237; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=78813237]").text(description); $(".js-view-count[data-work-id=78813237]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 78813237; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='78813237']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 78813237, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=78813237]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":78813237,"title":"Ultrafine coal dewatering: Relationship between hydrophilic lipophilic balance (HLB) of surfactants and coal rank","translated_title":"","metadata":{"abstract":"ABSTRACT Dewatering process is one of the most costly steps in mineral processing and coal washing plants.
