某重晶石型白钨粗精矿精选提质试验研究

摘要

对某选厂含WO37.24%、BaO 1.21%的白钨粗精矿进行了精选提质试验研究.在确定最佳条件后用彼得罗夫法加温精选,得到了WO3品位为37.79%、回收率71.80%的白钨精矿.该精矿含有20%左右的重晶石,以硫酸作为重晶石抑制剂进行钨钡分离,得到了WO3品位为62.06%的白钨矿精矿,回收率为65.61%,但实际生产中需解决酸对浮选设备的腐蚀问题.%The scheelite rough concentrate of a dressing plant contains 77.24%WO3 and 1.21%BaO.After determining the optimal conditions , a concentrate assaying 37.79%WO3 with a recov-ery of 71 .80%was successfully obtained by Petrov heating concentration .Due to the concentrate still contained 20%barite , the separation of scheelite and barite was conducted using sulfate acid as the depressant of barite .Finally, the WO3 grade and recovery of the scheelite concentrate were 62 .06%and 65 .61%, respectively .In addition , the acid corrosion of flotation equipment should be concerned in practical production .
