The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.

A conventional uranium mill is a chemical plant, usually built near the uranium mine. Uranium milling extracts uranium using the following process: Milling. Trucks deliver uranium ore to the mill, which is crushed into smaller particles before extraction (or leaching). Due to the very low concentration of uranium in the rock, immense amounts …

1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility. At this point, the ore is called run-of-mine material because there has been no treatment performed on it. There are three primary types of run-of-mine materials: Run-of-mine consisting of useful …
