One of the main reasons copper is avoided is because it is difficult to grind and it requires additional handwork after machining. This is due to the annoying burrs thrown up by machining, whether by milling or grinding. Flood coolant is a great way to avoid the burrs, however, most manual surface grinding operations do not use flood coolant.

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
