A primary or jaw crusher is located at the mine site and reduces the particle diameter of the ores into <6 in. The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration. The second stage, grinding, is a wet operation which requires initial flotation and water to make a slurry.

In mineral processing, all ores will have an optimum particle size which maximizes the economic benefits from the net smelter return while minimizing the cost of crushing and grinding. If the particle size is too coarse there will be inadequate liberation, limiting recovery (and thus revenue) in the separation stage.

Processing includes secondary surface crushing, stockpiles, grinding mills, froth flotation and storage. A traditional sulphide flotation process is used to recover copper and precious metals into copper concentrate containing gold and silver. It is designed to process both coppergold oxide and sulphide ore.
