The process of reducing mined ore for processing is known as 'comminution', which is defined as 'the action of reducing a material, especially a mineral ore, to minute particles or fragments'; this is normally achieved at mining operations through one or more stages of crushing and milling.. Early mining activities were labour intensive. Ore breakdown occurred via a miner's pick ...

After the crushing and milling process, the mineral is more suitable for further processing, which involves additional steps such as flotation, leaching, etc. The final product formed is then distributed to the market. Therefore, crushing and milling involve separating the mineral from the waste rock during the mining process.

In most industries size reduction falls into two general categories: crushing and milling. Crushing typically means reducing large chunks to sizes about 1/2 in. to 3/4 in. in diameter or smaller. Milling usually means reducing material to sizes in the low micron or even nanosize range. Crushing mostly is done dry while attrition milling may be ...
