Jun 18, 2005· The copper ore is crushed and ground before it is concentrated to between 20 and 40% copper in a flotation process. The next major step in production uses pyrometallurgical processes to convert the copper concentrate to 99% pure copper suitable for electrochemical refining .
The copper is extracted from sulphide ore by pyrometallurgy which involves reduction of the concentrated ore at high temperature. This process is a dry process. In this process, the sulphide ore is concentrated by froth floatation process. In this process, the sulphide ore is not concentrated by leaching with dil sulphuric acid.
