Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached).

The milling (refining) process extracts uranium oxide (U 3 O 8) from ore to form yellowcake, a yellow or brown powder that contains about 90 percent uranium oxide. [6] Conventional mining techniques generate a substantial quantity of mill tailings waste during the milling phase, because the usable portion is generally less than one percent of ...

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 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.

Dissolved or leached uranium is concentrated, purified, and dried to become the final product: yellowcake. After milling, other companies buy the uranium and enrich it in order to use the material as nuclear fuel. The milling process creates byproduct materials. This sandy waste is often referred to as tailings and contains heavy metals and radium.

Despite the name, the concentrated uranium product is typically a black or brown substance called yellowcake (U 3 O 8).Mined uranium ore typically yields one to four pounds of U 3 O 8 per ton of ore, or 0.05% to 0.20% yellowcake. The solid waste material from pit and underground mining operations is called mill tailings.The processed water from solution mining is returned to the …
