Autoclave Leaching of Copper Nickel Matte

The matte was preleached at atmospheric pressure to selectively extract 20 pct of the nickel, and the undissolved solids were referred to as the matte residue. Autoclave leaching of the matte residue extracted over 95 pct of the nickel, copper, and iron. The remaining leach residue in the autoclave contained over 100 oz of precious metals per ton.

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 .
