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.

(2005), outlines current thinking which relates to the formation of nickel-copper-PGE sulphide deposits similar to what Balmoral has discovered at Grasset. Within the ultramafic intrusion or flow, sulphide droplets form, often through contamination of the magma with sulphur from ...

NICKEL AND COBALT ORES: FLOTATION

The usual method of nickel extraction from sulRde ores is through the production of nickel matte after enriching the nickel content of the ore. This is com-monly carried out by magnetic separation, Sotation, or a combinationof both after the ore is comminuted to below 200 m in size. The enrichment depends

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Nickel Sulfide Versus Laterite : The Hard Sustainability ...

laterite compared to sulfide ores – leading to a historical preference for sulfide ores. To meet future demand for nickel, however, there is an increasing proportion of nickel being mined from laterite ores. This leads to an important issue in terms of the environmental costs of nickel – …
