Experimental Study on Improvement of Purification Process of Crude Na_2WO_4 Solution AITranslate
Abstract AITranslate
The traditional magnesium salt purification process is difficult to purify crude sodium tungstate solution with high As content （above 0.2 g/L）, so MgSO4-FeCl3 mixed method is put forward to purify the solution. Experimental results show that crude sodium tungstate solution with 0. 240.8 g/L As can be effectively purified by adopting 5 times the theoretical amount of MgSO4 solution at first and then adding 0.5 times the theoretical amount of FeCl3 solution under the conditions of 70℃ and pH9～10.
