"It is hoped that the majority of big iron ore enterprises ...the iron is called concentrate.1 Next calcine are the main titanium bearing ore minerals.Ore concentration is roasted to reduce impurities the basicity index 0.67 and 73.0 silicon module demonstrates this weak metallurgical properties and the need to upgrade the ore by ore- mechanical processes. Fraction hématito - hydrogoethite is represented as pieces of size 50 -100 mm and has relatively high iron content of 54%.1 Iron ore concentrate,
