| Abstract: | The new process of comprehensive utilization for phosphogypsum was presented.Ammonium sulphate with calcium carbonate as gross by-product could be obtained from the raw materials including phosphogypsum, ammonium bicarbonate and ammonia water. Calcium chloride was obtained by the reaction of hydrochloric acid with gross calcium carbonate, meanwhile the technological conditions of this reaction were determined. The quality of the obtained products reached the corresponding chemical standards and the application prospect of the products would be wide. |
