Copper Smelting Process - Brighthub Engineering

There are several methods of copper smelting, the popular ones being reverberatory smelting and oxygen flash smelting. Both methods require the resultant molten copper to be further processed to achieve a grade of 99.9% pure copper. During the process, the gas given off is converted to sulphuric acid, which can be used in the plant or sold off .
