Applications: Copper Compounds - Copper Sulphate

By heating copper scrap with sulphur to produce copper sulphide which is then oxidised to form copper sulphate. By heating copper sulphide ores to produce copper oxide which is then treated with sulphuric acid to form copper sulphate. By slow leaching in air of piles of low grade ore. Bacterial action is sometimes employed to hasten the process.

what properties does copper sulfide have? | Yahoo Answers

Dec 02, 2010 · A black colloidal precipitate of CuS is formed when hydrogen sulfide, H2S, is bubbled through solutions of Cu(II) salts.[4] It is one of a number of binary compounds of copper and sulfur (see copper sulfide for an overview of this subject), and has attracted interest because of its potential uses in catalysis[5] and photovoltaics."
