Cutting consumable costs is important for all mining operations, but not at the expense of quality. Grinding media represents low hanging fruit for most miners. Most often, the grinding media in question are grinding balls. In some mid-cap mines, grinding media makes up ~10% of total mining operational expenses (OPEX)

The Autogenous Mill, also known as AG Mill, is a type of grinding mill used in the mining industry. This machine uses ore and rock itself as grinding media to perform its job. Unlike other types of mills that use steel balls or rods for grinding materials, the Autogenous Mill relies on the material being ground to break itself into smaller pieces.
