Some Aspects of the Flotation of Sulfide Nickel

Flotation is affected by several factors, part of which depends on the mineralogical characteristics of the ore and part on process variabl Sulfide Ni-Cu ores occur typically in mafic and ultramafic igneous rocks Serpentine minerals are also common As a consequence of metamorphosis, sulfides and secondary minerals may be finely disseminated in an altered ore....
