The sizes of crushing and grinding plants must be matched to the type of ore (hardness, size of ROM ore, clay content, etc.) and the throughput of the processing plant. The purpose of crushing and grinding is to liberate or at least expose the surfaces of uranium minerals to allow the next stage of extraction.
