copper extraction and purification chemguide

2015-7-26  The process. The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage).

Extraction Of Copper Mining, Concentration,

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. \(Cu^{2}S + O^{2} → 2Cu + SO^{2}\) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2
