Milling Ore. Once at the production facility, it is put through a hammer mill to reduce it down to 200 mesh minus in particle size, then fluxed and roasted to reduce ore to an oxide. It is then ball milled with steel balls to a nano particle size, to achieve the highest yield and also the highest concentration level of whatever metal or element ...

Uranium Mining Overview. (Updated September 2021) In the last 60 years uranium has become one of the world's most important energy minerals. It is mined and concentrated similarly to many other metals. While uranium is used almost entirely for making electricity, a small proportion is used for the important task of producing medical isotopes.

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.
