The former mill processed uranium and other ores at the site between 1911 and 1957 and provided uranium for the U.S. government national defense programs. Standard Chemical operated the site as a radium extraction plant from 1911 to 1922. Later, Vitro Corporation of America acquired the property and processed ore to extract radium and uranium

Uranium mines and mills. Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada is one of the world's largest uranium producers. The majority of Canada's production is exported. Uranium is mined to provide uranium ore which is processed at a milling facility to produce uranium concentrate.

Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

Uranium as mined cannot be fed directly into a nuclear power station in contrast to coal, gas, or oil in a fossil-fueled power station. Uranium ore contains mineral and chemical impurities including radioactive daughter products of uranium. The uranium consists of 0.7% uranium-235 and 99.3% of uranium-238 isotopes.

Milling is a process to separate the uranium from the other metals and minerals in the rock, and to collect the concentrated uranium ore. The product is a fine yellow powder known as yellowcake, which is the basic raw material for manufacturing nuclear fuel. Even in the richest ore deposits, uranium makes up less than 20% of the total rock. In

Milling and processing. Conventional mines have a mill where the ore is crushed and ground to liberate the mineral particles, then leached in tanks with sulfuric acid to dissolve the uranium oxides. The solution is then processed to recover the uranium. With some South African uranium recovery from gold tailings, a pressure leach is necessary.
