Extraction Of Copper | Mining, Concentration, Smelting ...

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

Electrorefining of Copper

Fire-refined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques.

How copper is made

Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.

Copper

Copper was discovered at Kapunda in 1842 and mined until 1879, producing approximately 13 700 t of copper from 69 000 t of ore. A resource of 4.3 Mt at 1.1% Cu has been estimated in the supergene oxide and sulfide zone plus a large low-grade resource of primary chalcopyrite–pyrite mineralisation at depth.

Copper con | Kitco News

 · The metal content of copper ore has been falling since the mid 1990s. A miner now must dig up an extra 50% of ore to get the same amount of copper. As grade drops the amount of rock that must be moved and processed rises dramatically — all the while using more energy that costs several times more than it used to.

Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide.
