摘要
对新疆某锂品位0.68%的锂钽铌铍多金属矿进行了选矿试验研究。工艺矿物学研究结果表明,该矿石中锂矿物以锂辉石为主,钽铌矿物含量较低。采用磁选-重选回收钽铌、浮选回收锂的工艺流程,可得到Ta_(2)O_(5)品位17.110%、Nb_(2)O_(5)品位19.670%,回收率分别为41.69%、42.63%的钽铌精矿和Li2O品位5.12%、Li2O回收率75.21%的锂精矿。
A mineral processing test was conducted to treat a lithium-tantalum-niobium-beryllium polymetallic ore with a lithium grade of 0.68%from Xinjiang.According to the process mineralogy study,this ore has spodumene as the dominant lithium minerals,and has low content of tantalum-niobium minerals.A flowsheet including a magnetic separation and gravity separation to recover tantalum-niobium minerals,and a flotation to collect lithium minerals can produce a tantalum-niobium concentrate with Ta_(2)O_(5)grade and recovery of 17.110%and 41.69%,Nb_(2)O_(5)grade and recovery of 19.670%and 42.63%,respectively,and a lithium concentrate with Li2O grade and recovery of 5.12%and 75.21%,respectively.
