Indeed, mineralogy changes of Nb-hosting phases, their textural relationships with hydrothermal or secondary minerals, play a key control over mineral processing. This study based both on filed work and ore characterization presents data from several Nb-deposits related to carbonatite complexes. The results obtained by a wide range of analytical techniques, including, XRD, XRF, ICP-MS, SEM, Microprobe, Spectro-CL, FTIR-DTA and M枚ssbauer spectroscopy, demonstrate how geometallurgical assessment, at all stage of mine development, can greatly assist in the design of a suitable extraction flowsheet and data reconciliation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbonatites" title="carbonatites">carbonatites</a>, <a href="https://publications.waset.org/abstracts/search?q=Nb-geometallurgy" title=" Nb-geometallurgy"> Nb-geometallurgy</a>, <a href="https://publications.waset.org/abstracts/search?q=Nb-mineralogy" title=" Nb-mineralogy"> Nb-mineralogy</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20processing." title=" mineral processing."> mineral processing.</a> </p> <a href="https://publications.waset.org/abstracts/94088/geometallurgy-of-niobium-deposits-an-integrated-multi-disciplined-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94088.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Joint Simulation and Estimation for Geometallurgical Modeling of Crushing Consumption Energy in the Mineral Processing Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Khorram">Farzaneh Khorram</a>, <a href="https://publications.waset.org/abstracts/search?q=Xavier%20Emery"> Xavier Emery</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, it is aimed to create a crushing consumption energy (CCE) block model and determine the blocks with the potential to have the maximum grinding process energy consumption for the study area.

The analysis shows that TBCOSIM and plurigaussian have the more realistic results compared to cokriging. It seems logical due to the nature of the data geometallurgical and the linearity of the kriging method and the smoothing effect of kriging. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plurigaussian" title="plurigaussian">plurigaussian</a>, <a href="https://publications.waset.org/abstracts/search?q=turning%20band" title=" turning band"> turning band</a>, <a href="https://publications.waset.org/abstracts/search?q=cokriging" title=" cokriging"> cokriging</a>, <a href="https://publications.waset.org/abstracts/search?q=geometallurgy" title=" geometallurgy"> geometallurgy</a> </p> <a href="https://publications.waset.org/abstracts/182716/joint-simulation-and-estimation-for-geometallurgical-modeling-of-crushing-consumption-energy-in-the-mineral-processing-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182716.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> A Method for Rapid Evaluation of Ore Breakage Parameters from Core Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Nguyen">A.

This paper presents a method for rapid prediction of ore-specific breakage parameters from high resolution mineral classified core images. The aim is to allow for a rapid assessment of the variability in ore hardness within a mineral deposit with reduced amount of physical breakage tests. This method sees its application primarily in project evaluation phase, where proper evaluation of the variability in ore hardness of the orebody normally requires prolong and costly metallurgical test work program. Applying this image-based texture analysis method on mineral classified core images, the ores are classified according to their textural characteristics. A small number of physical tests are performed to produce a dataset used for developing the relationship between texture classes and measured ore hardness. The paper also presents a case study in which this method has been applied on core samples from a copper porphyry deposit to predict the ore-specific breakage A*b parameter, obtained from JKRBT tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geometallurgy" title="geometallurgy">geometallurgy</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperspectral%20drill%20core%20imaging" title=" hyperspectral drill core imaging"> hyperspectral drill core imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20simulation" title=" process simulation"> process simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=texture%20analysis" title=" texture analysis"> texture analysis</a> </p> <a href="https://publications.waset.org/abstracts/68239/a-method-for-rapid-evaluation-of-ore-breakage-parameters-from-core-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68239.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">361</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> The Comparison of Joint Simulation and Estimation Methods for the Geometallurgical Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Khorram">Farzaneh Khorram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper endeavors to construct a block model to assess grinding energy consumption (CCE) and pinpoint blocks with the highest potential for energy usage during the grinding process within a specified region. Leveraging geostatistical techniques, particularly joint estimation, or simulation, based on geometallurgical data from various mineral processing stages, our objective is to forecast CCE across the study area. The dataset encompasses variables obtained from 2754 drill samples and a block model comprising 4680 blocks. The initial analysis encompassed exploratory data examination, variography, multivariate analysis, and the delineation of geological and structural units. Subsequent analysis involved the assessment of contacts between these units and the estimation of CCE via cokriging, considering its correlation with SPI. The selection of blocks exhibiting maximum CCE holds paramount importance for cost estimation, production planning, and risk mitigation. The study conducted exploratory data analysis on lithology, rock type, and failure variables, revealing seamless boundaries between geometallurgical units. Simulation methods, such as Plurigaussian and Turning band, demonstrated more realistic outcomes compared to cokriging, owing to the inherent characteristics of geometallurgical data and the limitations of kriging methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geometallurgy" title="geometallurgy">geometallurgy</a>, <a
