Sherritt Gordon Process. 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 content of laterites varies widely at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ.

May 03, 2018 This process has three steps 1. Nickel oxide reacts with Syngas at 200 C to give nickel, together with impurities including iron and cobalt. NiO (s) H2 (g) Ni (s) H2O (g) 2. The impure nickel reacts with carbon monoxide at 5060 C to form the gas nickel carbonyl, leaving the impurities as solids.
The natural product for a leaching process is a high grade nickel intermediate either from a direct precipitation process (containing approx. 36% Ni) or via ion exchange (50% Ni). There are many existing pyrometallurgical facilities which could easily be adapted to take this nickel intermediate giving them significant potential benefits ...
