THE DEVELOPMENT OF MINING AND MINERALS PROCESSING IN SOUTHERN AFRICA Gold mining by the indigenous people of Africa, as distinct from trading in gold along the east coast, was carried on from as early as 500 A.D in the Early Iron Age until some point in the early 19 century. In the first millennium AD gold was principally obtained
Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …
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 …
