摘要: 应用自行研制的新型捕收剂QAS224,对Al2O3品位为64%左右、铝硅比为6.1左右的河南某铝土矿矿石进行反浮选脱硅试验,结果在磨矿细度为-0.074 mm占81.24%,矿浆pH为11的条件下,通过1次粗选、2次精选、2次扫选,获得了精矿Al2O3品位为67.79%,Al2O3回收率为81.72%,铝硅比为9.67的较好指标。试验结果证明QAS224是铝土矿反浮选脱硅的有效捕收剂。

Abstract: With application of a new self-developed collector QAS224,the reverse flotation de-silicatation tests on a bauxite in Henan with Al2O3 grade of 64%,Al-Si ratio of about 6.1 were made through a process of a roughing- two cleanings-two scavenging.The results showed that under grinding fineness of -0.074 mm 81.24% and pH 11,a concentrate with Al2O3 grade of 67.79%,Al2O3 recovery of 81.72% and Al-Si ratio of 9.67 can be obtained.Hence,QAS224 was an effective collector in reverse flotation de-silicatation of bauxite.
