Improving copper flotation recovery from a refractory ...

01/07/2011  The bench-scale flotation tests were performed in XFD-63 flotation cell (self aeration) whose volume for rougher flotation was 3.0 dm 3, for separation flotation of copper/iron sulfide minerals was 1.0 dm 3 and for cleaner flotation was 0.5 dm 3, respectively. The rougher flotation used 1 kg ore to obtain a Cu/Fe rougher concentrate, then two Cu/Fe rougher concentrates were mixed

Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage. In 2015, personnel from Buenavista del Cobre and Outotec conducted a process assessment of the rougher flotation stage. The process assessment included detailed mineralogical characterisation of an ore sample, a sampling campaign bank-by-bank
