| Abstract: | A new process of producing potassium sulfate and ammonium chloride with waste phosphogypsum has been developed. The other raw materials includes ammonium bicarbonate and potassium chloride. Calcium carbonate and ammonium chloride are produced as by-products. The flow has advantages of short range,easy operation,lower cost and a better quality of production. The conversion of K + was more than 88.23% and the production content of potassium sulfate was more than 92.10%. |
