The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a "speiss", rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.
20-04-2021· Another advantage that this creates is there is now a supply of Lithium and Cobalt that doesn't need mining and as a significant refining process for the renewables and electronics industry. A key challenge for the renewable industry will be balancing the geopolitical, economic, environmental issues that will arise as the industry grows.
