采矿和冶金生产给周围环境造成巨大损失。例如,在克里沃罗格矿区每年要排弃300Mt剥离废石和100Mt选厂尾矿。排土场和尾矿库要占用土地13ha。露天矿爆破、破碎、选矿和烧结厂排放的粉尘和气体、排土场和尾矿库的风蚀都给大气造成严重污染。为了形成生态净化的采矿冶金生产环境,很有必要将含铁石英岩的选矿加工转入
Mining and metallurgical production have caused huge losses to the environment. For example, 300 Mt decontamination of waste rock and 100 Mt of mill tailings are to be abandoned annually in the Krivoy Rug mine. Dumping sites and tailings ponds will occupy 13ha of land. Blast and crushing of open-pit mines, dust and gas from the beneficiation and sintering plants, and wind erosion of the dump and tailings depot all cause serious pollution to the atmosphere. In order to create an ecologically clean mining and metallurgical production environment, it is necessary to shift the beneficiation of ferrous quartzite into
