ROASTING OF SULFIDE MINERALS

ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. Sulfides are not reduced with the most widely used redu-cing agents, carbon and hydrogen, because the free energy change for the ...

copper extraction and purification - chemguide

In the copper(I) sulphide, the copper is +1 and the sulphur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. In sulphur dioxide, the oxygen has an oxidation state of -2 and the sulphur +4. That means that both the copper and the oxygen have been reduced (decrease in oxidation state).

Copper(I) sulfide - WikiMili, The Best Wikipedia Reader

Copper monosulfide is a chemical compound of copper and sulfur. It occurs in nature as the dark indigo blue mineral covellite. It is a moderate conductor of electricity. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H 2 S, is bubbled through solutions of Cu(II) salts. It is one of a number of binary compounds of copper and sulfur (see copper sulfide for an overview of ...
