How copper is made material, used, processing, steps

The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.
