Handbook of Flotation Reagents | ScienceDirect

The nickel silicates are treated using either pyrometallurgical or hydrometallurgical methods. 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

Beneficiation of low-grade weathered nickel sulfide ore

Processing nickel sulfide minerals by flotation always presents the challenge of obtaining appropriate selectivity between nickel sulfide and other sulfides, such as pyrrhotite, pyrite, and chalcopyrite. Other minerals that can reduce the process efficiency and the concentrate quality include minerals that contain magnesium (e.g., talc). Most
