A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Milling Ore Once at the production facility, it is put through a hammer mill to reduce it down to 200 mesh minus in particle size, then fluxed and roasted to reduce ore to an oxide. It is then ball milled with steel balls to a nano particle size, to achieve the highest yield and also the highest concentration level of whatever metal or element is desired to be processed.

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.
