4 Uranium Mining, Processing, and Reclamation

For uranium ore deposits, the choice of mining methods and processing options is very deposit-specific and dependent on many variables such as the quality and quantity of the ore, the shape and depth of the ore deposit, site-specific environmental conditions, and a range of other factors. Accordingly, the description of how uranium mining is undertaken in this report is generalized and at a ...

DISPOSAL OF RADIOACTIVE WASTE IN THE VITRO-TYPE

A study was made of possible modifications in conventional uranium ore- processing steps to confine and permit controlled disposal of radioactive wastes. A potential method of minimizing pollution from radioactive nuclides, principally radium-226, in uranium mill waste streams is to reuse the waste solutions within the mill. Such reuse of waste solution in the Kerr-McGee Shiprock-type process ...

Uranium processing Britannica

Uranium processing, preparation of the ore for use in various products. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.
