提高胂酸对金红石浮选性能的研究

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。

A STUAY ON PROMOTING THE COLLECTION PERFORMANCE OF ARSENIC ACID IN RUTILE FLOTATION

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.
