BK414在宜春钽铌矿浮选锂云母的工业试验

摘要

BK414为北京矿冶研究总院自主开发的新型锂云母浮选药剂。针对宜春钽铌矿钽铌重选尾矿，以BK414作为捕收剂进行锂云母浮选工业试验，获得锂云母浮选指标：浮选给矿Li2 O品位1.08％，锂云母精矿Li2 O品位3.79％，Li2 O回收率63.09％。与宜春钽铌矿目前所使用的椰油胺相比，采用BK414所获得的锂云母精矿回收率提高了8.07％。BK414具有选别指标好、凝固点低、腐蚀性小等优点。%BK414 was a new lepidolite flotation reagent developed by Beijing General Research Institute of Mining and Metallurgy.For the tantalum & niobium gravitation separation tailings with a Li2O grade of 1.08% from Yichun tantalum & niobium ore ,a concentrate of 3.79% Li2 O with a recovery of 63.09%could be obtained with BK414 as a collector through lepidolite flotation industrial test.Compared with cocoanut oil amine which had been used in Yichun tantalum & niobium ore ,the lepidolite concentrate recovery could be improved by 8.07% with BK414 as a collector.BK414 has the advantages of good flotation index ,low freezing point ,little causticity and so on.
