The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammer ...

Abandoned mine and mill sites, including for uranium, are eligible to be listed as Superfund or NPL sites, but historically only about 70 abandoned uranium mines and mills have been listed as Superfund sites, more than 30 of which still remain on the Superfund list. Three uranium mines are currently on the National Priorities List.

The mill was built in 1979 to process uranium ore from the surrounding region. About a decade later, the mill's operator also started running "alternate feeds" through the mill and discarding the resulting wastes onsite. These feeds include uraniumbearing radioactive and toxic wastes from other contaminated places around the country.

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 ...
