Oxygen Pyrometallurgy at Copper Cliff

In view of the economic superiority and metallurgical potentialities of the new process it is recommended that a first step 400 tpd copper concentrate flash smelting unit and a 300 tpd oxygen plant be installed at Copper Cliff

Extraction Of Copper Mining Concentration Smelting

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 Cu2S O2 2Cu SO2 The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2

metallurgy and hydrometallurgy copper Industrial

This process consumes 2500 to 3000 kWh t 1 of copper produced The copper is deposited on the cathode and the gases produced at the anode O 2 C 2 are recovered selectively and returned to the process This method produces an extremely pure copper that can then be rolled hot or cold drawn or even formed into tubes before being sold
