In order to develop methodological approaches to substantiation of quality management systems for mineral raw materials and to refine the technologies and criteria for ore types zoning in the quarry space, the possibilities of individual techniques for preliminary assessment of the qualitative properties of ores were analyzed. Using the geological database for the Gusevogorskoye titanomagnetite ore deposit, an analysis of the methods for preliminary assessment of qualitative characteristics of the mineral was performed. A statistical evaluation of the detailed exploration data for the quarries of EVRAZ KGOK OJSC is presented and regression equations are obtained for the interconnection of the grades of valuable components in the ore. Based on the generalization of the existing criteria for the evaluation of titanomagnetite ores of the Gusevogorskoye deposit, the complex dressability index is established, which is then used to build mining and geometric models and to perform ore types zoning on the example of the Northern quarry. Calculations are performed to establish the contrast index for the titanomagnetite ore within the Northern quarry. The results of block modeling using forecast ore contrast values within the horizon of +160 m are presented. The scientific results obtained will serve as the basis for subsequent studies on improving the mine planning methodology in the quality management of mineral raw materials and increasing the efficiency of ore dressing.
The studies were carried out within the framework of State Assignment No.007-00293-18-00, subject No.0405-2018-0002, project No. 18-5-2345-56 titled «Development of the Earth’s interior: Substantiation of ore conditioning methods for deep complex processing of mineral raw materials and increasing metallurgical production performance».
