Abstract
Removal of fluoride in the nitrophosphate process was firstly investigated. Precipitation tests were performed both in pure fluoride solution (H2SiF6Â +Â HFÂ +Â H2O) and actual acid digestion liquor using KNO3 as precipitant. The results revealed that the addition of KNO3 would remove the fluoride effectively, and the obtained precipitates were the high-purity K2SiF6.
