A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada, one of the world's largest uranium producers, accounts for 18 percent of global production and exports 90 percent of its uranium. Uranium is mined so it can be processed at a milling facility in order to recover the uranium concentrate.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

Milling. For both traditional underground and open pit mining, the rocks may have only a few percent (normally <%) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry.
