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 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister Copper;

How do you convert copper oxide to copper chloride

Sep 14, · You need 2 molecules of HCl for every one of Copper (II) Oxide. So for every 79.545g of copper oxide you have, you need 72.92g of HCl. To get this much HCl, you need 231.86g of HCl solution (72.92g/0.3145). This much HCl is contained in 199.88 mL (231.86g / 1.16g/mL). The ratio you need is thus 199.88 mL of 31.45% HCl per 79.545g of CuO.
