crushing and grinding process in uranium plant in united states

Conventional Mining

The uranium "boom" period of the late 1970's and early 1980's witnessed considerable growth of the uranium mining industry in the United States, including development of large open pit, underground, and in-situ recovery operations. Many mining and milling production centers remained in operation through the middle 1980's, however, continuing price erosion ultimately

The uranium-bearing solution pumped from a mine unit is piped to the Central Process Plant (CPP) or satellites for extraction of the uranium by use of down flow ion exchange (IX) columns to remove the uranium. As the solution passes through the resin in the IX column, the uranium is preferentially removed from the solution by attachment to the resin.
