Pyrite, the most widespread and abundant of sulphide minerals in the Earth's surficial rocks, commonly constitutes the primary opaque phase in ore deposits. Consequently, an understanding of the behaviour of pyrite and its relationships with coexisting phases during the metamorphism of pyritebearing rocks is vital to the interpretation of their ...

The sulfide minerals are a class of minerals containing sulfide (S 2−) or disulfide (S 2 2−) 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

The reaction produces secondary sulfides with metal contents higher than those of the primary ore. This is particularly noted in copper ore deposits where the copper sulfide minerals chalcocite (Cu 2 S), covellite (CuS), digenite (Cu 18 S 10 ), and djurleite (Cu 31 S 16) are deposited by the descending surface waters.

At high-temperature pressure leaching conditions, the formation of sulphuric acid from sulphides in the ore is favoured, however at medium- and low-temperature conditions (150-165oC and >140oC, respectively) elemental sulphur formation occurs. At these temperatures, the elemental sulphur is molten and causes issues in further leaching.

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. How do you identify sulphide ore?

Cobalt is concentrated when primary sulphide and silicate ore minerals are subjected to chemical and physical changes associated with atmospheric leaching. Where laterites have developed over a substratum of mafic or ultramafic igneous rocks, nickel and sometimes cobalt, is frequently concentrated in the weathered zone ( Crockett et al., 1987 ).

Cinnabar, mercury sulfide (HgS), is the principal ore of mercury. (more below) Cinnabar is very dense, 8.1 times as dense as water, has a distinctive red streak and has hardness 2.5, barely scratchable by the fingernail. There are very few minerals that might be confused with cinnabar, but realgar is softer and cuprite is harder.
