Treatment of Nickel-Cobalt Laterites

1. Nickel and cobalt can usually be solubilized from laterites using sulphuric acid at atmospheric pressure, just below boiling point. However, this generally requires a massive quantity of acid, which can render the process uneconomic. The main reason for this is that for limonitic ores in particular, the

Laterite-nickel ore

EXTRACTING. About 80% of the world''s copper-from-ore originates in Cu-Fe-S ores, such as chalcopyrite (CuFeS2) and chalcocite (Cu2S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu (open pit mines) to 1 or 2% Cu (underground mines). Cu-Fe-S minerals are not easily dissolved by aqueous ...
