Abstract AITranslate

Investigation is made on the low-concentration, low-addition HCl digestion of scheelite concentrate. The results show that the average digestion rate can reach 97. 35% in 1. 5 hour at 95~10℃ with the addition of HCl (10% concentration ) .1. 5 times more than the theoretical value. Compared with the traditional acid digestion process, the said process can bring about large reduction of HCl consumption and concentration, resulting in large reduction of waste acid treatment cost and elimination of HCl gas volatization during acid digestion. In this way, the working conditions are improved and the cost for the control of HCl gas pollutant for environmental protection is also reduced. However, the said technology doesn't remove Mo and needs larger acid liquid volume (1. 5 times as much as that of the traditional technology).
