Nickel / cobalt mining extraction procedures

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.

The Nickel Mining Process It's not unexpected that the mining processes for nickel differ because nickel is found in two quite different forms of ore. Although some deposits were mined using open pits in the early phases, …

Nickel Smelting and Refining

Nickel Refining Various processes are used to refine nickel matte. Fluid bed roasting and chlorine-hydrogen reduc-tion produce high-grade nickel oxides (more than 95% nickel). Vapor processes such as the carbo-nyl process can be used to produce high-purity nickel pellets. In this process, copper and precious metals remain as a pyrophoric residue that re-
