Nickel processing | Britannica

With nickel found in two radically different types of ore, it is not surprising that the mining methods differ. Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open pits in the early stages.

The benefit of treating a laterite ore pyrometallurgically is that you utilise a greater percentage of the resource as the iron and nickel become a product, by way of example for 1,000,000 tonnes of ore mined, you might make 300,000 tonnes of product with a nickel grade of 6-10%. The remaining residue is usually a dry glass type material that is inert and can be used for earthworks or just
