Turning Copper Ore into Copper: What are the Processes?
Globally, approximately 80% of copper production is taken from various sulfide sources. Despite what the type of ore is, or where it is derived from, mined copper ore must first be treated so that unwanted materials within the ore are removed. This involves concentration, crushing, and powdering ore in a ball or rod mill. Sulfide and …

THE OPTIMAL BALL DIAMETER IN A MILL
The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Ball Mill
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
