This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore) Having a quick look now at how porphyry ores are treated and the metals extracted
The above flowsheet shows a basic copper mine process, from mine to metal There are two distinct types of copper ore, the sulfide ore and the oxide ore The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached First the copper ore from a open pit mine is blasted, loaded and transported to the primary .
We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process Mining for Copper Bearing Ore There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different .
