Copper Nickel Flotation

Flotation responses were studied in both laboratory and pilot plant tests. Pilot plant flotation responses were similar for both samples resulting in grades of 12.2 pct Cu and 2.5 pct Ni for the pit sample and 12.2 pct Cu and 2.1 pct Ni for the shaft sample. Weight recoveries were 2.5 pct for the pit sample and 5.2 pct for the shaft sample.NICKEL AND COBALT ORES: FLOTATION,tively separate Cu}Ni ores from pyrrhotite gangue in the absence of a collector, but with SO 2 and an,III/NICKEL AND COBALT ORES: FLOTATION 3493.
