Study on Dissolution Behavior of CaSO4-WO3System in H2SO4Solution AITranslate
Abstract AITranslate
By using the method of bisulfate and tungsten ore roasting,arsenic in tungsten ore could be converted into volatile arsenide and absorbed by the alkaline solution,fundamentally changing the easy-dispersion trend of arsenic in the tungsten smelting system and greatly reducing the formation of the arsenic-containing hazardous waste in tungsten smelting.Simultaneously,the tungsten ore is roasted into MnSO4,Fe2(SO4)3+WO3or CaSO4+WO3products,and the next step is to separate tungsten and impurities in the roasted products effectively to obtain relatively pure tungsten compounds.In general,MnSO4and Fe2(SO4)3could be effectively dissolved by cheap sulfuric acid,but whether CaSO4and WO3could be dissolved in the same way is unknown.Based on this,the dissolution behavior of CaSO4-WO3system in sulfuric acid was systematically studied in this paper.The results show that in the sulfuric acid system,the solubility of CaSO4is significantly greater than that of WO3,and their solubility difference varies little with the concentration of sulfuric acid but greatly with temperature.The effective separation of CaSO4and WO3can be achieved by controlling certain acidity and temperature.
