摘要:
为了得到常温反浮选铁矿脱硅脂肪酸阴离子捕收剂,实现常温反浮选,通过植物油脂肪酸原料的选取,磺化、氧氯化反应再复配阴离子表面活性剂,制备阴离子型捕收剂. 以李楼铁矿工业生产的二段强磁尾矿试验样品,进行了常温反浮选脱硅. 试验结果表明,以棉油脂肪酸为原料合成的捕收剂的浮选性能优于米糠油脂肪酸和玉米油脂肪酸;在药剂中复配少量的表面活性剂MES能提高药剂的捕收性能;采用反浮选工艺流程,在矿浆温度为17 ℃条件下,获得了铁精矿全铁质量分数65.91%,产率62.76%,回收率91.61%的浮选指标.
Abstract:
To obtain ideal anionic collectors for reverse flotation of iron ore at normal temperature, different kinds of plant fatty acids were used to prepare anionic collectors by chemical reaction of sulfonation, oxidation, oxidation and then by compounding a certain amount of surfactant. The results of reverse flotation in Lilou strong magnetic tailings in second stage indicate that the flotation property of collector made by cottonseed fatty acid is better than that of rice bran fatty acid and corn fatty acid, and could be improved by compounding a small amount of surfactant MES. Beneficiation indexes of 65.91% iron concentrate grade,62.75% yield and 91.61% recovery rate are obtained with reverse flotation at 17 ℃.
