In some copper concentrators, the mill feed is all passing 13MM(½"), using three stages of crushing and 14MM (9/16″) square openings on the closed circuit screens. It was felt by some that crushing to this fine size is only possible if the ore is friable and is relatively soft in comparison to the harder ores.

However, concentration methods such as froth floatation separate the copper minerals from the waste rock for more tricky ores, such as sulfide ores. The sulfide ore is then roasted or smelted into a purer copper concentrate called a slab. Finally, the copper slab undergoes electrolysis, resulting in 99.99% pure copper cathode slabs.
