Three stages of crushing reduce the size of the ore from 18 inches, to 4 inches, and finally to less than ½ inch. GRINDING Grinding is conducted in two ball mills where 3 inch chrome balls reduce the ore from less than ½ inch to 80 microns, creating a texture similar to fine sand. Water is added to the pulverized ore to create a slurry. FLOTATION

Most commercial balls are made of steel with a carbon content of about 0.5 to 1.0 wt % and heat treated to maximize resistance to abrasion, fracture, and spalling. Fully hardened balls have a tendency to fracture and spall. The odd shaped "balls" found inside ball mills are a result of fracture and spalling which result in higher ball consumption.
