Study on the Separation of Tungsten and Tin by Pre-roasting of Tungsten Concentrate AITranslate
Abstract AITranslate
Based on the analysis and investigation of SnO2 and Cu2FeSnS4＇s thermodynamic difference in caustic soda leaching,the influence of roasting pretreatment on the leaching ratio of tin was studied.Results show that in caustic soda leaching process,SnO2 is very hard to leach with leaching rate close to zero,while the leaching rate of Cu2FeSnS4 is much higher,which can reach 40%~50% under normal leaching conditions.Upon oxidization and roasting of the tungsten concentrate,the leaching ratio of stannum can be greatly reduced.At roasting temperature 700～800 ℃,roasting duration 2 h,the tin sulfides in Cu2FeSnS4 can be fully all converted into SnO2,and the leaching ratio of tin is reduced from 5.96% down to about 1%.
