摘要
针对内蒙古某微细粒浸染、易泥化难处理金矿石,进行了选矿工艺试验研究。结果表明,采用阶段磨矿—重选抛尾—阶段选别的工艺流程,可以获得金精矿金品位68.12 g/t、金回收率81.31%的较好指标。氰化浸出可回收部分浮选尾矿中金,进一步提高金总回收率。
Mineral processing technology study was carried out on a Inner Mongolia refractory gold ore which micrograined-disseminated and easily to be slimed. The results showed that adopting a technological processes with stage grinding,discarding tailing via gravity concentration and stage flotation,a gold concentrate with gold content and recovery of 68. 12 g / t and 81. 31% can be obtained. Cyanide leaching of flotation tailings can further improved the total gold recovery.
