摘要
以海口磷矿为原料进行二水-半水法萃取磷酸试验研究,试验获得了二水-半水工艺制取磷酸的优惠工艺条件。该工艺条件下获得的磷收率较二水流程高2个百分点,获得的磷石膏质量达建材石膏要求。
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.
