Hydrometallurgy, or “hydromet” for short, is a metal processing technology that uses a chemical process combining water, oxygen or other substances in a pressurized or other vessel to dissolve a metal from its ore, concentrate or an intermediate product (such as matte). The nickel industry worldwide has traditionally smelted concentrates ...

Nickel/Cobalt purification. Cobalt is a brittle, hard transition metal with magnetic properties similar to iron. It is mainly used as an alloy with iron, nickel or other metals to produce corrosion and wear resistant products for high temperature applications (such as jet engines, gas turbines, etc.). Cobalt is normally produced as a by-product ...

If you are referring to laterite Ni-Co leaching, HPAL is a well established process (Moa Bay, Murrin Murrin, Coral Bay, Ambatovy, etc.). It is essentially an acid digestion, but recovery is increased and residence time shortened through the use of high temperatures (255 ° C -270 ° C) which in turn need high pressure (4,000 kPa – 5, 300 kPa). ). These conditions need the titanium lining ...
