ABSTRACT:
Uranium ore is crushed and formed into a slurry. The slurry is pumped into a leaching tank and classified by a sparge tube projecting water at teeter velocity at the bottom of the ore bed. Thereafter, a second ore bed is pumped by the slurry into the tank and the second bed classified. This is repeated until there are four or five ore beds in the tank.
Thereafter, the ore is leached by passing liquid up from the bottom of the tank at velocities less than teeter velocities so that the bed remains classified.
After leaching, the ore is formed into a slurry and the slurry pumped from the tanks to disposal.
