摘 要：<正> The effect of different decomposition conditions on tungsten recovery for scheelite concentrate has been exam-ined. The results show that tungsten recovery can be more than 98% under decomposing conditions as follows: the amountof caustic soda is 2.2 and 3.2 times of theoretical respectively, ratio of wate and ore is 0.7-0.8, temperature is 160℃, andpreservation time is 2.0 h for scheelite concentrate （63.21% WO3） and low grade scheelite concentrate （55. 17% WO3）.
