Uranium Ore assaying approximately 0.25% U3O8, slightly under 1% V205 and 6.5% CaCO3 is received at the mill from company owned and operated mines and from custom ore suppliers. Virtually all of the production from the company mines is carnotite-roscoelite ore from the Salt Wash of the Morrison formation.

3 • Ammonia is used to raise pH • Ammonium di-uranate is precipitated • De-watering process – thickener drum filters • Roasting process at 830°C • Product quality is more than 98% U3O8 .Final Product Recovery • Optimum precipitation takes place at pH 7.
In milling, the mined ore is crushed, and a second extraction process chemically leaches the uranium from the ore and concentrates it to produce a material, which is called "yellow cake” because of its yellowish colour.

The mill was left abandoned along with several million tons of unprocessed ore. In 1946, the plant was torn down and a new one built on the site to recover uranium. Vanadium is still used in the process of hardening steel. Additional ores were mined and milled for the uranium content from other sites in Colorado.
This process is repeated to remove as much uranium as is economically feasible. When mining at the site is complete, the groundwater will be restored to its original quality. This is a closed loop recirculation system since the water from the production well is reintroduced in the injection wells.
