- Process Flow Of Copper Milling
The next stage, smelting, is a process of heating and melting the copper concentrates to cause a chemical reaction, which removes the copper from other elements in the ore. At the smelter, we produce large 750-pound anodes and transport them by rail to the Refinery. The copper is 99 percent pure at this stage.

The mill shaft is powered by a motor and gearbox arrangement. The high packing density of the grinding media produces strong friction, which causes efficient grinding of the product. The variable speed of the milling shaft allows for an energy efficient grinding process to reach the required product particle size.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
