Static leaching process for recovering uranium mineral values
Description
A description is given of a static leaching process for recovering uranium mineral values from a permeable bed of ore comprising: 1) drying the ore in an agitated state to increase permeability of the ore bed, 2) placing the dried ore into a leaching vessel, 3) adding a lixiviant solution to the ore bed to leach the mineral values from the ore under pressure sufficient to cause flow of the solution through the bed of core, 4) percolating the lixiviant solution through the ore to leach the mineral values from the ore, 5) adding a sweep fluid to the ore to sweep the lixiviant containing dissolved mineral values through the bed of ore, and recovering an effluent lixiviant solution from the bed of ore containing the uranium mineral values.
