During milling the uranium bearing ore is initially crushed (if preceded by conventional mining), which is typically a dry process, and then ground into a slurry, which is a wet process. The intent of crushing and grinding is to effectively increase the surface area to volume ratio of the material, which facilitates chemical leaching.

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 ...

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 ...

In a narrow sense "grinding" is used (also referred to as friction grinding in mining). "Grinding" refers to pulverization in the area of finer particle size (crushing of fine particles) and may be distinguished from crushing. Besides these, "milling", etc. are also used. Thinky Corporation uses "pulverization".
