材料生产所有各部门的迅速发展,要求加紧开发自然资源。有色冶金企业1913年从矿石中回收了Д.И.门捷列夫化学元素周期表中107种元素中的15种,而1930年为20种,1940年为24种,1950年为43种,1960年为63种,1980年达到74种。今后补充有色冶金工业原料基地的途径将是,探明并开发新的原料产地,降低原料的开采标准,更加合理地综合利用采出的原料资源。这一最后的方向具有非常重要的意义。
The rapid development of all sectors of material production calls for intensified exploitation of natural resources. In 1913, non-ferrous metallurgy companies recovered 15 of the 107 elements of the Mendeleev Periodic Table of Chemical Elements from ores in 2013, compared with 20 in 1930, 24 in 1940, 43 in 1950, 63 in 1960 and 74 in 1980. The way to supplement the base of non-ferrous metallurgy industrial raw materials in the future will be to identify and develop new sources of raw materials, lower the mining standards for raw materials, and make more rational use of the raw material resources harvested. This last direction is of great importance.
