Handbook of Flotation Reagents | ScienceDirect

The reagent practice in the flotation of nickel and copper–nickel ores depends on three basic factors: mineralogy of the ore, flowsheet employed in the treatment of a specific ore, and degree of liberation. The presence of hydrophobic gangue represents a major problem in the treatment of both nickel and copper–nickel ores.
