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 …
In the early 20th century, production was irregular due to the decrease of the copper price ... Through the cleaning process, the slag is crushed and submitted to flotation again, but this time the Mo in its oxidized state reports to the tailings and, hence, is deposited on the tailings heap in the slag rich layer. Therefore, the missing step ...
