- grinding of uranium ore
Uranium ores are normally processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. A conventional uranium mill is a chemical plant, usually built near the uranium mine. Uranium milling extracts uranium using the following process: Milling.

The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.

uranium rises exponentially with falling ore grade. At a grade below 0.02% U 3O 8, 200 ppm, or 200 grams per Mg (metric ton) the mass of ore equals the mass of coal consumed by a coal-fired station to generate the same amount of electricity: this is the coal equivalence.

Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium – that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade.
