The analysis of technological factors affecting the efficiency of interaction between mining and processing and mineral resource complexes is given. For the first time it was proposed to use the recoverable value of mineral raw materials as an indicator that unites both stages of mineral and raw materials complex development. The ways of increasing the reliability of technological assessment, in the process of which the extractable value is determined, are indicated. The models of expert systems of rational subsoil use are proposed: certification of mineral raw materials by technological properties (extractable value); quantitative assessment of the degree of rationality and complexity of subsoil use, technological audit of subsoil use and others. The role of expert systems in creating a mechanism of accounting and control over subsoil use, effective management of the state subsoil fund is shown.
A rational series of technological solutions aimed at improving the efficiency of study and development of deposits and including seven stages is proposed: predictive assessment of ore contrast in the subsurface, assessment of the contrast of extracted ore of initial size, operational technological assessment of the obtained grades, ore preparation with the use of centrifugal-impact type apparatuses, maximum use of gravitational processes with full or partial abandonment of flotation schemes, enrichment of technological grades obtained by large lump processing The complex of innovative technologies for gold-sulfide, gold-quartz, copper-silver ores and copper ores with gold mineralization is given. The developed rational range of technological solutions is used in the creation of the concept of antimony industry development in the Republic of Sakha (Yakutia).
