由于金属的世界需求量增长较快,因此促进了从自然资源中回收金属的生产。这样,就需要通过矿物原料的综合利用,改善合理利用金属及提高从矿石中回收金属的程度。在稀有金属生产中处理矿物原料的综合方法具有特殊的意义,稀有金属在地壳中的分布有限,因而回收和冶炼稀有金属是比较困难的。在处理标准的和非标准的原料时,三氧化钨和钼的总回收率(对矿石)分别为60—70%和55—60%,而钨、钼的损失主要在选矿阶段(表1)。因此,将非标准中矿和精
Demand for metals from the natural world is boosted by the rapid growth in demand for metal in the world. In this way, there is a need to improve the rational use of metals and the degree of recovery of metals from the ore through the comprehensive utilization of mineral raw materials. A comprehensive approach to the processing of mineral raw materials in the production of rare metals is of particular interest. The distribution of rare metals in the crust is limited, so that recovery and smelting of rare metals is more difficult. The total recoveries of tungsten trioxide and molybdenum (for ores) were 60-70% and 55-60%, respectively, for both standard and non-standard feedstocks, while the losses for tungsten and molybdenum were mainly at the beneficiation stage (Table 1) . Therefore, non-standard mining and fine
