Studies in Leaching of Sulphide Concentrates of Copper and Nickel from Indigenous Source

The work reported in this paper in on the leaching of sulphide concentrates obtained as a bye-product of the beneficiation of an indigenous source of Uranium Ore. The ore body also contains small amount of tourmaline, magnetite, biotite, apatite and sulphides. The sulphides consist of chalcopyrite and pentlandite, nickelferous pyrrhotite and pyrite, violarite, bravoite, millerite - all containing nickel and molybdenite. These sulphides assayed approximately Ni 0.11-0.2% Cu 0.15-0.25% and M0 0.03% in addition to small amount or uranium values in a bulk concentrated.
