Waste Guide for the Uranium Milling Industry

Process steps which are basic to all mills, however, are crushing, grinding, leaching wherein the uranium is dissolved from the crushed ore, and recovery. The latter step involves the selective re- moval of the uranium from the leaching solution for prepara- tion of the concentrated product.
