Effect of phosphate rock particle size on recovery of uranium from superphosphate

摘要

The tremendous domestic reserves of phosphate rock together with the large annual production of normal superphosphate from phosphate rock have made the recovery of the small amounts of uranium (0.01 to 0.02 percent) in phosphate rock during the production of superphosphate an important problem. At current superphosphate production rates there exists a uranium potential of approximately 1000 tons per year.
