The Russian Federation holds the fourth largest reserves of titanium dioxide in the world. The “typical” deposits of titanium are, for instance, magmatic titanium-magnetite deposits of Gusevogorskoe and Sobstvenno-Kachkanarskoe. The process types of ore and its concentration laws have been found from a research. An innovative approach to dividing titanium–magnetite ore into process types for the improvement of concentrate quality and reduction of processing cost is substantiated. The discussion covers the data on preparabilty, grindability and magnetic rigidity of various natural types of titanium-magnetite ore. The article identifies trends of development in the metallurgical industry, describes experimentation and reports experimental results. The basis is given for blast furnace-converter processing circuit for high-titanium and low-titanium concentrates. The lab test smelting has been performed to divide pellets of high-titanium (HT), low-titanium (LT) and master concentrate (MC) of Gusevogorskoe deposit ore into pig iron and slugs. The calculation data on composition of raw material stock for blast-furnace smelting, namely, agglomerates and pellets, obtained using the balance logical-statistical model show that metallurgical properties of the resultant concentrates are different. The actual ore preparability classifications are presented, and the algorithm of the low-titanium and normal-titanium ore geometrization is described. The results are reported as the horizon-oriented layouts and tables. The analysis of the ore flow logistics at a processing plant (from receiving bins on the cone crushing floor to concentrate warehouse) has shown that it is quite feasible to process separately two ore flows at the plant of the Kachkanar Mining and Processing Integrated Works. The authors put forward a mi ning strategy in the mode of quality control for the Sobstvenno-Kachkanarsky deposit. The perspectives of the project implementation are specified.
