RSM优化硫化锑矿浮选试验研究
|
摘要
本文将RSM应用于硫化锑矿浮选试验的条件优化,为RSM在锑矿选矿中的应用提供参考和借鉴。原矿经磨矿后经硫酸铜活化,以丁胺黑药和丁基黄药按1∶1混合作为捕收剂,采用RSM对试验进行设计,经回归分析和优化预测,得到最佳浮选条件为:磨矿细度为-0.074mm占64.46%,硫酸铜用量为234.42g/t,捕收剂用量为173.24g/t。并在最佳试验条件基础上进行闭路试验,最终得到锑品位51.16%,产率8.66%,回收率93.84%的锑精矿。
RSM was applied to optimize the conditions of flotation test of antimony sulfide ore.Copper sulfate was used as activator after grinding.Butylamine aerofloat and butyl xanthate were mixed by 1∶1 as a collector.Through design,regression analysis and optimization prediction,the conditions of flotation optimized by RSM were as follows:grinding fineness of-0.074 mm,accounting for 64.46%,the dosage of copper sulfate was 234.42 g/t and the collector dosage was 173.84 g/t.The closed circuit test was carried out on the basis of the best test conditions.Finally,the grade of Sb in concentrate was 51.16%,the yield of 8.66%in antimony concentrate,and the recovery rate of Sb was 93.84%.
