development of flotation technology, which originated in Broken Hill at the start of the 1900s, is presented. The development of the original Potter-Delprat process, the introduction of oils to generate froth flotation and the achievement of selective flotation processing are described, all focussed on solving challenges with the Broken Hill Pb-Ag-Zn ores. Some recent initiatives in flotation at BHP Billiton operations are also outlined, covering coal, copper, lead-silver-zinc and diamonds. Some views are offered on the characteristics of innovation in flotation and on possible trends into the future.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="0274a74be5ad641f8ec837a8c6ea1695" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":70894144,"asset_id":54612686,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/70894144/download_file?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="54612686"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="54612686"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 54612686;

To design a bubble generation system for the full scale column circuit extensive tests have been run with the pilot column, which is instrumented to measure all process flows, froth depth, gas holdup and bubble diameter. Two sparging systems have been studied." a cloth sparger and the external contacting system.

It is based on measurement of conductivity to estimate gas holdup using a multi-cell probe. The technique is demonstrated on air/water in a 0.91 m脳 13.5 m flotation column equipped with Cominco-type spargers. With 15 ppm Dowfroth, three spargers gave a W-shaped profile at gas rates (Js) less than 0.9 cm/s while a saddle-shaped profile was observed at Js= 2.2 cm/s. With 1 centrallylocated sparger, the profile was saddle-shaped even at Jg = 0.6 cm/s; one off-centre sparger gave a nonaxisymmetrical profile but nevertheless showed good distribution of gas. The maximum absolute variation in radial gas holdup was about 4% under all conditions; for practical purposes this could be considered uniform distribution.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6067e626f1fa006310867630d043b53d" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":70894138,"asset_id":54612683,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/70894138/download_file?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="54612683"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="54612683"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 54612683;

The results from this column have been used to design a full scale column circuit to treat all of the Cu-Ni separation feed. To design a bubble generation system for the full scale column circuit extensive tests have been run with the pilot column, which is instrumented to measure all process flows, froth depth, gas holdup and bubble diameter. Two sparging systems have been studied." a cloth sparger and the external contacting system. This paper reports the bubble generation characteristics and metallurgical performance of the two systems.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="daad00bb980f39088aa8d19bf799cb1f" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":70894137,"asset_id":54612684,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/70894137/download_file?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="54612684"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="54612684"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 54612684;

It is based on measurement of conductivity to estimate gas holdup using a multi-cell probe. The technique is demonstrated on air/water in a 0.91 m脳 13.5 m flotation column equipped with Cominco-type spargers. With 15 ppm Dowfroth, three spargers gave a W-shaped profile at gas rates (Js) less than 0.9 cm/s while a saddle-shaped profile was observed at Js= 2.2 cm/s. With 1 centrallylocated sparger, the profile was saddle-shaped even at Jg = 0.6 cm/s; one off-centre sparger gave a nonaxisymmetrical profile but nevertheless showed good distribution of gas. The maximum absolute variation in radial gas holdup was about 4% under all conditions; for practical purposes this could be considered uniform distribution.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6067e626f1fa006310867630d043b53d" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":70894138,"asset_id":54612683,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/70894138/download_file?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="54612683"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="54612683"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 54612683;
