摘要 采用长沙矿冶研究院研制的新型阴离子反浮选捕收剂CSC-68和新型调整剂CSR-36对袁家村铁矿石磁选精矿进行了反浮选试验,并与传统的NaOH+淀粉+CaO+脂肪酸阴离子捕收剂4药剂组合进行了对比。试验结果表明:采用两种新药剂的组合,可获得品位为66.06%,回收率为87.19%的反浮选铁精矿,精矿铁品位和回收率分别比传统4药剂组合高0.96和0.87个百分点。新药剂不仅选别指标优越,而且大大简化了药剂制度,还可避免因使用CaO而引起的管道结垢问题。 A new type of anionic reverse flotation CSC-68,and a new modifier CSR-36 developed by Changsha Research Institute of Mining and Metallurgy were adopted to make the inverse flotation tests on magnetic separation concentrate for Yuanjiacun iron ore,and then test results are compared with that of four reagents combination of the traditional NaOH + Starch + CaO + fatty acid anions collector.The results showed that by combining two new agents,the iron ore concentrate in reverse flotation with grade of 66.06% and recovery of 87.19% are obtained. The ratio of iron grade and recovery with the traditional four reagents combinations are higher by 0.96% and 0.87% respectively. New agents are not only superior in beneficiation index, but also can greatly simplify the agents system. Moreover, scaling problems in the pipeline caused by CaO can be avoided.
