摘要
摘要通过对金红石矿石浮选研究发现:用苄基胂酸(BAA):非离子型表面活性剂(F2):离子型表面活性剂(E4)配比为l:l:002组成复合捕收剂(BF2/E4)浮选原生金红石矿石,结果粗精矿品位为75.41%,回收率68.25%;而单一BAA浮选金红石粗精矿品位为76.24%,回收率66.89%,这两者结果是很相近的。在捕收剂总用量不变条件下,复合BF2/E4中的BAA用量只有单一BAA用量一半,而且F2来源广,价格低,无毒。使用BF2/E4后,不仅提高了浮选作业回收率,而且该作业成本将降低1/3左右,环境污染也相应地减轻了。
The test of rutile flotation had found the coarse flotation concentrate is 75. 41 % TiO2, withrecovery of 68. 25 % by using compoiste collector (BF2/E4) to float rutile. The TiO2, conteut of coarse con-centrate is 76. 24 % with recovery of 66' 89 % by using single BAA as a colleetor of rutile flotation. Both re-sults are about the same. The BF,/E4 consists of benzyl arsenic acid (BAA), non-ionic surfactant (F2) andionic surfactant (E,) in proportion as 1: 1: O. O2. On this condition of using same quantity colleetors tofloat rutile, the quantity of the BAA in composite BF2/E4 is half as large as single BAA used as collector,meanwhile, F2 distribution is extensive, its price is low and F2 is norpoisonous- By using BF2/E4 as rutileflotation collector, not only the flotation recovery of rutile will enhance, but also flotation cost will cut downabout l/3. The composite collector BF,/E4 will also reduce the environment pollution.
