| Abstract: | Pilot study on dihydrate - hemihydrate process for WPA production with Haikou phosphate rock as raw material was done. The optimum conditions of the dihydrate - hemihydrate process were obtained. Compared with dehydrate process, the phosphorus recovery rate was improved by 2 percentage points, the quality of phosphogysum met the request of building gypsum. |
