Extraction Of Copper Mining, Concentration,
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 sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

Copper In History CopperSmith
2014-10-18 · This much ore could produce 18 tons of pure copper and used up to 315 tons of coal in 38 furnaces, according to records from the Mines Royal at Neath Abbey in Wales. The downside to producing copper in such quantities was that the sulfur in the copper ore polluted the air, creating fumes of sulfur dioxide around refineries.
Copper Mining and Extraction Sulfide Ores
About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and
