recoverable uranium, it is necessary to process from 500 to 5000 kg ore for each kilogram of uranium recovered. To produce the same amount of uranium, therefore, millsize can vary by a factor of 10. Most uranium mills use wet grinding, and the resulting slurry is fed to .
EFFECTS OF MINERAL CRUSHING ON THE LEACHING OF .
The relation between leaching and the degree of monazite crushing was studied with ThX, U, RdTh, and Th. The results showed that variations in leaching of minerals depend on the changes in the mineral surface and the adsorption properties of the surface. () Authors: Starik, I E; Lazarev, K F.

In Situ Leach Mining (ISL) of Uranium
In situ leaching (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to the surface where the minerals can be recovered. Information from the World Nuclear Association, the global privatesector organization that provides information on nuclear power, nuclear energy, and the role of nuclear in sustainable development.

Waste Guide for the Uranium Milling Industry
Uranium mills employ acid or alkaline leaching to dissolve the uranium content of the ore following grinding. Once the uranium has been put into solution, it is recovered by chemical precipitation, which, in some cases, is preceded by a concentra tion step in which ionexchange or solventextraction methods are used.

3rd ed., Vol. XXIII, 1983, p. 504.
Uranium ore is recovered using either conventional mill ing or solution mining (in situ leaching). Beneficiation of conventionally mined ores i nvolves crushing and grinding the extract ed ores followed by placement in a leaching circuit. In situ operations use a leach solution to dissolve desirable uraniferous minerals from inplace deposits.

following steps: ore crushing, heap leaching with sulfuric acid, uranium purifiion by solvent extraction technique and uranium precipitation as ammonium diuranate – ADU [1]. As the openpit mine became deeper, the uranium recovery in the leaching step dropped due to the presence of primary uranium minerals locked in the rock grains.
