苏联哈萨克斯坦有色冶金系统废料场已堆存各种废料48亿吨,几乎占该共和国全部工业废料的三分之一。其中矿山废石占7、2％,选厂尾矿大约占四分之一,冶金废渣占2.5％。与全国一样,哈萨克斯坦每年矿物原料的开采总量递增6％。苏联矿物原料的开采量已占全世界的26～27％,转化的成品率却不超过百分之十几,其余的都以废料形式堆存在废料场或尾矿坝。尽管精矿的金属回收率已经很高,但选场尾矿量仍然很大,占固体废料总量的
The Soviet Union’s non-ferrous metallurgy system scrap yard in Kazakhstan has stocked 4.8 billion tons of waste, accounting for almost one-third of all industrial waste in the Republic. Of these, 7,2% were mines and mines, about a quarter was tailings from the plant, and 2.5% were metallurgical residues. As in the whole country, the total amount of mining of mineral raw materials in Kazakhstan increases by 6% annually. The Soviet Union has taken up 26-27% of the world’s mineral raw materials and the conversion rate does not exceed 10%. The rest is scrapped in waste yard or tailings dam. Although the metal recovery of concentrate is already high, the amount of tailings in the field is still very large, accounting for the total amount of solid waste
