Sulfide Ore - an overview ScienceDirect Topics

Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte. A key element in the recovery of the metals is the ...

Sulfide mineral - Wikipedia

The sulfide minerals are a class of minerals containing sulfide (S ) or persulfide (S2 ) as the major anion. Some sulfide minerals are economically important as metal ores. The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts. Sulfide minerals are inorganic compounds.

A fresh approach to sulfide ores - CIM

26-06-2017  The traditional route for extracting copper from sulfide ores is smelting. Yet there is a growing case for leaching sulfides from lower grade ore bodies and especially for those ore bodies containing problematic elements like arsenic, which make smelting less economical. Smelting is increasingly expensive because, in general, smelters require a ...

Many sulfide ores contain Pt, Au, Ag, Cd, In, Se, and Te as admixtures. Most deposits of sulfide ores are endogenous, and among those, hydrothermal deposits predominate. The ore bodies are most often veins, but they may also be sheets, lenses, stocks, and pipes. The length and depth of such bodies range from hundreds of meters to several ...
