Copper sulphide (CuS) has a covellite structure that consists of a hexagonal phase and P6 3 /mmc phase group. The existence of these metal sulphides is found in many mineral forms with general formulae (Cu x S y) such as villamaninite (CuS 2), covellite (CuS), digenite (Cu 2 S 5), chalcocite (Cu 2 S), several others.
Thiol collectors were used in the froth flotation of copper sulphide from the slag. The xanthates, dithiophosphates are classes of thiol collectors that each form different surface products on different copper sulphide minerals. It has been shown that the use of mixtures of thiol collectors can have benefits over the use of pure collectors ...

Uses of Copper Compounds: Copper Sulphate. Copper sulphate, blue stone, blue vitriol are all common names for pentahydrated cupric sulphate, Cu S04 5 H20, which is the best known and the most widely used of the copper salts. Indeed it is often the starting raw material for the production of many of the other copper salts.
Copper sulfide (Cu x S) was also used to detect acetone for a very high level of concentration [23]. Lead sulfide (PbS) and cadmium sulfide (CdS) were used to sense methanol (750 ppb to 1000 ppm) [16], [32]. The detection limit for methane and acetaldehyde by CdS and SnS 2 is 2500 ppm and 10 ppm respectively [32], [49], [50].
Copper is most commonly present in the earth's crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S).
Abstract-The direct sulphation of individual and mixed sulphides of copper and iron has been studied. using a steam-oxygen mixture as the oxidant. The investigation showed that copper sulphide ...
Chalcopyrite CuFeS 2, secondary copper sulfides (covellite CuS, chalcocite Cu 2 S) and bornite Cu 5 FeS 4 have an economic value among copper minerals of sulphide deposits of the Urals.
