摘要: 针对朝鲜某大型碱性花岗岩型钽铌锆矿床矿石化学成分复杂,有用矿物嵌布粒度细,有用矿物之间以及与脉石矿物之间解离性差的特点,采用细磨—脱泥—钽铌锆混合浮选流程处理该矿石,在原矿Nb2O5、ZrO2、Ta2O5品位分别为1.17%、3.12%、0.046%情况下,最终可获得Nb2O5、ZrO2、Ta2O5品位分别为9.43%、24.95%、0.36%,回收率分别为77.37%、76.77%、75.13%的钽铌锆混合精矿。

Abstract: Aiming at a large alkaline granite type tantalum niobium zirconium deposit with characteristic of complex ore chemical composition, fine dissemination size of useful mineral, poor dissociation of useful minerals and gangue mineral, fine grinding - desliming - bulk flotation of tantalum and niobium, zirconium was used to process this ore.A bulk concentrate with 9.43% of Nb2O5 and 24.95% of ZrO2 and 0.36% of Ta2O5 with a recovery of 77.66% Nb2O5 and 76.70% ZrO2 and 75.13% Ta2O5 was obtained by closed-circuit test from the raw ore with grade of 1.17% Nb2O5 and 3.12% ZrO2 and 0.046% Ta2O5.
