Flotation of Nickel and Nickel–Copper Ores

Flotation of nickel from this ore [3] is quite difficult and requires very high collector additions In contrast nickel flotation from massive ores such as Voisey Bay (Canada) requires very little collector [4] due to the fact that nickel-bearing minerals are relatively floatable
