In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually Ball or SAG mills. Inside these Sag/Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed.

Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.
The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

Mine call factor issues from a surface mine perspective. The theory of mine call factor (MCF) compares the sum of metal produced in recovery plus residue to the metal called for by the mines evaluation methods expressed as a percentage.
Other articles where Mine cutoff grade is discussed: mining: Delineation: This is called the mine cutoff grade. And, if the material has already been mined, there is a certain grade below which it is not profitable to process it; this is the mill cutoff grade. The grade at which the costs associated with mining and mineral processing just equal.
