Upgrading Sishen Iron Ore Slimes by Reverse Cationic
Batch flotation tests were conducted on a haematitebearing Sishen iron ore slimes sample from South Africa using reverse cationic flotation. The effect of grinding on flotation performance, the flotation response of various key impurities in the sample, and the feasibility of increasing metal recovery by refloating tailings in a scavenger flotation step were investigated.
