First, expounds the decomposition of phosphate rocks and the transformation of phosphogypsum, then examines the inactivation of phosphate rocks and CaSO_4-H_3PO_4-H_2O system, finally states the pilot results:40%~50% P_2O_5 of product, 99.26% of P_2O_5 recovery, 5.5 hours of reaction time, over 50% of escaped fluorine; 140% filteration area of dihydrate process and less tank volume, quite pure by-product phosphogypsum with less than 0.2% P_2O_5.Read More
