摘　　要：介绍了某矿山含硅酸铁矿石、碳酸铁矿石及原生矿的组成并进行了选矿试验研究,结果表明,3种矿石中原生矿最好选,含碳酸铁矿石最难选。根据试验结果,可以实现难选矿石与易选矿石合理配比,避免大量难选矿石同时给入生产时造成的生产指标波动。该研究对采场和选厂有一定的指导意义。The compositions of three iron ores in a mine, ore containing iron silicate, ore containing iron carbonate and the primary ore, were analyzed, and a beneficiation research was conducted. The results show that the primary ore can be beneficiated most easily, while ore containing iron carbonate is the hardest to be recovered. A blending feed of the easy-to-handle and the refractory ores with a rational ratio is recommended, to avoid the fluctuation of processing index due to the excessive feed of refractory ore. The results may provide an instruction for the production practice in both mining fields and concentration plants.
