AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG ...

Ion exchange involves the following two stages: (1) loading/absorption and (2) elution. During stage (1) the solution is in contact with the ion exchange resin permitting selective adsorption of uranium. During stage (2), uranium is stripped from the resin yielding a uranium-rich solution called "eluate."
