Abstract
Mineral values, particularly uranium, are recovered from mineral containing ore by separating the ore into a coarse fraction and a fines fraction, adding a diluent solid material, such as a portion of barren coarse fraction to the fines fraction and leaching the thus diluted fines fraction with a leach solution. The coarse fraction is separately leached, preferably under mild conditions of temperature and leach solution concentration. In another aspect, the total ore is leached, preferably under mild conditions, the thus leached ore is separated into a coarse fraction and a fines fraction, the fines fraction is again leached and at least a part of the leached fines fraction from the second leach step is recycled to the first leach step.
