摘要
辉铋矿与闪锌矿、磁铁矿共生的多金属矿石较少见 ,具有一定的典型性。对某铋锌铁多金属矿石进行了选矿试验研究 ,结果表明 ,采用优先浮选法选铋、锌 ,磁选法选铁的选别工艺 ,可较好地回收矿石中的辉铋矿、闪锌矿和磁铁矿。试验发现这种矿石中的辉铋矿的浮选行为有一定特殊性 。
Polymetal ore containing bismuth glance, sphalerite and magnetite is rarely seen and typical. Beneficiation tests were made on certain bismuth zinc iron polymetal ore. The results show a technology consisting of bismuth and zinc separation by preferential flotation and iron concentration by magnetic separation can well recover bismuth glance, sphalerite and magnetite from this ore. It is found that the flotation behaviour of bismuth glance is special and only in weak acidic medium and by using activator can good flotation indexes be obtained.
