Copper Mining and Processing: Processing of Copper Ores

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.

Direct Reduced Iron

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF rout In DRI, iron ore is reduced in its solid state - unlike BF process where a liquid metal is formed during reduction DRI can then be transformed to steel in electric arc furnac DRI production is common in Middle East, South America, Kenya and Mexico.
