Surface chemistry in relation to flotation selectivity: TOF-SIMS surface analysis of mineral phases from metallurgical tests in flotation circuits - Surface Science Western

Request for analysis: Metallurgical testing on a poly metallic Cu/Pb/Zn ore indicated either copper or lead activation of sphalerite in a Cu/Pb flotation test. Objective: To establish and rank the factors controlling sphalerite flotation. Methodology: The surface composition of individual sulphide grains was examined by TOF-SIMS and comparative analyses of the surface chemistries on sphalerite grains from the feed, concentrate (fast floating particles) and tails (rejected particles) were...
