在黑色冶金工业中,氧化含铁石英岩的工业利用问题,近年来已成为重要问题之一。这与苏联现有的一些铁矿企业顺便采出的氧化矿数量增加有关。仅在库尔斯克磁力异常区,当开采磁铁石英岩时,每年顺路采出1200—1500万吨含铁37—45％的氧化矿石。这种矿石暂时未经选矿,而貯存在专用的貯矿場。因此,在“1981—1985和到1990年期间的经济和社会发展主要方向”一文中,对黑色冶金工业提出了任务:“掌握在工业生产条件下氧化含铁石英岩选矿和球团
In the black metallurgy industry, the industrial utilization of oxidized ferrous quartzite has become one of the important issues in recent years. This is related to the increase in the amount of oxide ore taken by some of the existing iron ore mines in the Soviet Union. Only in the Kursk magnetic anomaly area, 12-15 million tons of ore containing 37-45% of iron ore are produced on an annual basis when mining magnetite quartzite. This ore is temporarily untreated and stored in a dedicated storage yard. Thus, in the article “The main directions of economic and social development during the period 1981-1985 and 1990”, the task was given to the black metallurgical industry: "to master the oxidation of iron-bearing quartzite in industrial production conditions and pellets
