Nickel Sulfide Versus Laterite : The Hard Sustainability ...

Nickel is commonly present in two principal ore types – sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).

Ore deposits formed by oxidation and supergene enrichment

Ore Deposits Formed by Oxidation and Supergene Enrichment · When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. · The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. · An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to ...

Then ...

Nickel sulfide - Wikipedia

Nickel sulfide is an inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide.Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.Aside from being useful ores, nickel sulfides are the products of desulfurization reactions, and are sometimes used as catalysts.
