nickel sulphide grinding

Some factors that affect beneficiation of sulphide nickel ...

Jun 01, 2007  Alkaline pH depresses particularly pyrrhotite but does not have a significant effect on chalcopyrite. Nickel recovery is moderate and remains between these two. The sulphide depression after ceramic grinding is probably a consequence of the adsorption of hydrophilic compounds on sulphide surfaces . Process iron increases the depressing influence.

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. Nonstoichiometric formsof nickel sulfide are known, e.g., Ni9S8 and Ni3S2. Nickel can also combine with more than one sulfur atom per nickel atom, as in the mi
