Initial rougher and cleaner floatation test work from

2019-1-29A total of 5 rougher and four cleaner floatation tests were conducted. The intent of the flotation testing was to produce a high grade mixed cobalt nickel concentrate, focussing on recovery of cobalt. Given the small number of tests completed, optimisation testing was limited and several potential areas for improvement remain

Flotation of Gold and Gold

2016-1-11. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, 1939, Richards and Locke, 1940,

A Brief Review of Pulp and Froth Rheology in Mineral

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.
