copper extraction and purification

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

BE1002035A3 - Method for in pyrometallurgical copper

If a blast furnace is used this copper is charged to a converter where the purity is increased to about 80 to 90 percent and then to a reverberatory furnace where copper of about 99 percent purity is achieved The final step is known as fire-refining In these pyrometallurgical processes flux is added to the copper and air is blown upward
