NICKEL AND COBALT ORES: FLOTATION

2016-6-7  The nickel extraction process is dictated by the min-eralogical assemblage of the ore. Pyrrhotite rejectionhas been of no real importance in many mills treatingsulRde ores except in countries having strict restric-tions on SO2emission. Pyrrhotite rejection from pent-landite is not very satisfactory in the plants adoptingdifferential Sotation, but recent investigationsindicate the possibility of employing SO2and DETAbesides adopting starvationSotation.
