Copper exists as a variety of sulfides, and the most common stoichiometric sulfide is chalcocite Cu 2 S. However, copper also forms a number of non-stoichiometric sulfides such as digenite (Cu 9 S 5), anilite (Cu 7 S 4), and yarrowite (Cu 9 S 8), and copper exists in mixed-valence states, namely, as Cu I and Cu II. Although the sulfide …

A mine is supplying copper sulphide concentrate to a smelter/converter complex to produce blister copper, sulphuric acid and waste slag (35wt % FeO − 65 wt % SiO 2 ). As the mining operation proceeds the concentrate grade from the associated mineral processing plant is maintained at 25% copper but the form of the copper changes over …

All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur. The copper sulfide is oxidized by Fe 3+.The resulting Fe 2+ is reoxidized to Fe 3+ by O 2.The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevated-temperature reaction conditions where the sulfur-containing product …

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
