Assessment of the current state of the fresh groundwater resource base southern regions of the Komi Republic

The state of the resource base of fresh underground waters of the southern regions of the Komi Republic (RK) is assessed. The distribution of groundwater reserves by the administrative-territorial objects of the south of the Komi Republic, by geological and hydrogeological structures, by 83 explored deposits of drinking and industrial groundwater is analyzed. The volumes of groundwater production in 2019 are given. A low degree of development of the resource potential and groundwater reserves is noted. The degree of development of reserves does not exceed 6 %. The degree of knowledge of groundwater is 1 %. The aquifers (horizons) of fresh groundwater of the research area are characterized.

Problems of boxite processing and enrichment, waste management

The problem of enrichment of aluminum ores is due to the fact that bauxite-forming minerals have similar density, dispersed character and subtle intergrowth. Therefore, the development and improvement of methods for the enrichment and processing of bauxite continue. The work shows the effect of physical and chemical factors on iron minerals with the goal of transforming them into magnetite, to increase the magnetic phase. Influence of various kinds of energetic influences on bauxite raw materials and red mud is established, under which the magnetic properties and phase composition change, the concentrations of certain minerals change.

Role of technological researches in development of the mineral raw materials complex of the Timan-North Ural region

Actual problems of a technological assessment of mineral raw materials of the Timan-North Ural region are considered. The role of scientific developments in development and effective use of mineral resources of the region is shown. Results of technological researches of coals, oil shale, bauxites, titanium ores, industrial minerals are given.
