摘要
湖南某钨矿日产生钨细泥100～200t,该钨细泥WO3品位4.68%,钨矿物主要为黑钨矿.黑钨矿、白钨矿的粒度极微细,粒度小于0.01mm的黑钨矿和白钨矿分别占其总量的62%和79%,回收难度较大.根据该钨细泥的矿物特性,采用"强磁选-浮选"工艺,并用新型改性水玻璃SA作为抑制剂,对钨细泥中的钨矿物进行了有效回收,最终获得钨精矿品位(WO3)43.01%、回收率81.16%的指标.
About 100 to 200 t tungsten slime with a grade of 4.68% WO3 was produced in one tungsten mine in Hunan a day. The tungsten slime consists mainly of wolframite. The grain size of both wolframite and scheelite in the ore is very fine,their particles size of less than 0.01ram account for about 62% and 79% respectively,so it is difficult to recover. Based on the mineralogy characters of the tungsten slime,the magnetic separation-flotation flowsheet with the new kind of modified water glass SA as depressor was used to recover tungsten mineral from tungsten slime. Finally, the tungsten concentrate assaying 43.01 WO3 with the recovery of 81.16% can he obstained.
