| Abstract: | Based on the high impurity content, poor colour, low utilization rate of by-product phosphogypsum of WPA production by traditional method, the new production technology of WPA and by-product opal paste is invented. With the new technology, the by-product opal paste of WPA production is with the low impurity content and can be fully utilized. Based on the yield of WPA, about 50 million tons opal paste should be produced with the value of tens of billions RMB Yuan per year. |
