Metal Extraction Processes for Electronic Waste and ...

Copper smelting is the dominating route for e-waste recycling where PMs are collected in copper matte or black copper. In the final stage of copper production, i.e. , the electrorefining process, pure copper metal is produced and the PMs are separated into slimes where they are recovered using

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
