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 99 99% pure copper called cathodes which will ultimately be made into products for everyday use The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

Zinc smelting producing and classification

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc The most common zinc concentrate processed is zinc sulfide which is obtained by concentrating sphalerite using the froth flotation method There are two methods of smelting zinc the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in
