    A Brief Review Of Pulp And Froth Rheology In Mineral Flotation

    Jul 13, 2020 Table 1 summarizes selected results from the historical flotation test work programs. The 1997 flotation tests were undertaken on a relatively high grade sample (23 g t gold) and produced high grade concentrates ( 1000 g t gold) with flotation recoveries between 68 and 82 . Only rougher flotation was undertaken in the 1997 test work program.The Kamoa Kakula joint venture between Ivanhoe Mines, Zijin Mining and the DRC government, has awarded Glencore Technology a contract for the supply of Jameson flotation cells for Phase 2 of the project (3.8 Mt y to 7.6 Mt y). It covers the supply of a model E4232 10 Jameson Cell in a high grade cleaner duty and a model B4500 12 in a scavenger re cleaner duty.

    In the cleaner scavenger cell 90, the concentrate 92 is recycled back to mill 80 for regrinding and feeding to the Jameson cell scalper 60. The cleaner scavenger tails 93 is fed to the final tail stream 200. The results from this two stage testing are shown in FIG. 5. These indicate excellent recovery from the scalper and further good stability.In mineral flotation, rheological problems have limited the efficient upgrading of low grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
