1. Introduction. Iron ores, according to the iron content and the level of impurities, can be divided into two groups. The first group is high-grade iron ores containing high iron content and low content of impurities (Беспояско, 2014).This type of ore is quickly exhausted, since it is widely used in a blast furnace process for iron smelting.
