Copper Smelting Process And Methods

Copper Smelting Process - Furnaces Used, By …

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 ...

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
