copper refining processing methods

Copper Smelting Process - Furnaces Used, By-Products, copper refining processing methods ,Historically, copper bearing ores contain only about 06% copper, the remainder being gangues or unwanted minerals Chalcopyrite ore is in this range and can be mined by underground or surface methodsCopper Purification Process - Electrolytic Copper Refining ,Copper Anodes: In copper processing, a copper anode is an intermediate product from the smelting furnaces which is used as a copper source from which to make copper cathodes during electrolysis In electrolysis, it is the positive terminal.
