  • Flotation Of Nickel Laterite

    · Flotation Of Nickel Laterite by S PermanaThe laterites generally have been regarded as being completely refractory to beneficiation by froth flotation and indeed the only commercial beneficiation which is presently known to be carried on consists in a size separation whereby a particular laterite deposit situated in the western United States is beneficated from approximately 14 to 16 percent nickel by removal of a coarse sizeFLOTATION OF LATERITIC NICKEL ORES WESTON D,CADevelopments in Flotation Flotation of Nickel Sul\de Minerals Collectorless Wotation It is known that chalcopyrite and pyrrhotite can be Soated without collectors at electrode potentials of #400 mV and #50 mV respectively, and pyrite does not Soat even at #700 mV The underlying mechanism causing hy drophobicity, although obscure, is attributed to surface oxidation, formation of elementalNICKEL AND COBALT ORES: FLOTATION
