本文描述了从难选的多金属结合矿石中提取有用成分的新方法，如在破碎磨矿前采用辐射法预先把物料分为矿石和废石；对矿石进行选择解高；利用电化学能、热能、加速电子能走向改变矿物的表面特性，以利于选矿，把选矿过程和火冶、水冶过程结合起来；从而大大提高了金属回收率和产品质量，降低了成本。本文还涉及到了堆置于尾矿库中的尾矿综合利用的问题以及环境保护问题。 This article describes new methods for extracting useful constituents from refractory polymetallic ores, such as the use of radiation to separate the material into ores and waste rocks prior to crushing and grinding, the selective elevation of ores, the use of electrochemical energy, Thermal energy, accelerated electrons can change the surface properties of minerals to facilitate the beneficiation, the beneficiation process and fire Ye, water metallurgy process together; thus greatly improving the metal recovery and product quality and reduce costs. This article also covers the problems of comprehensive utilization of tailings piled in tailings ponds and environmental protection issues.
