Currently in the world, in the mining and metallurgical industry there is a forced need to reduce the share of processing ores and increase the share of previously accumulated industrial wastes. A phased concept of the use of man-made waste is proposed. At the first stage, the existing industrial wastes are considered as resources and are subject to complete processing with the minimum amount of new waste. At the second stage, the task is to develop non-waste technologies. The example of Uzbekistan (Navoi and Almalyk MMC) shows one of the possible options for the integrated use of industrial waste for …

The article presents the results of sulfur purification research with an inorganic adsorbent released as waste during the production of vanadium pentoxide from spent vanadium catalyst. High purification of liquid sulfur from organic impurities, ash and acids is achieved by treating the molten sulfur with an inorganic adsorbent, followed by separating the purified sulfur by filtration. The silicate base of the spent vanadium catalyst is used as the inorganic sorbent after vanadium pentoxide is removed from it. The consumption of the silicate base of the spent vanadium catalyst after removal of vanadium pentoxide from it is regulated in the range …

This article provides laboratory research data on the analysis of the ash of combustible shale from the Sangruntau deposit and the possibility of their enrichment. Magnetic enrichment of the ash of combustible shale was carried out in order to determine the yield of the magnetic fraction, determine the chemical composition of the products of magnetic separation, determine the extraction and the enrichment factor for the main elements. When gravitational enrichment of the ash of combustible shale gold almost completely goes into the gravity concentrate. Gravitational enrichment of rhenium, vanadium, copper, zinc, uranium does not occur.
Based Deformation Monitoring Of Laser Scanning Systems On The Network Of Observational Stations Of The Deep Mine Of Jsc Pimcu, A.A. Tokin
Gorniy vestnik Uzbekistana
For successful forecasting and prevention of shock hazard situations, scientific and methodological recommendations on deformation monitoring based on laser scanning systems on the network of observation stations of the Gluboky mine of JSC PIMCU have been developed. The description of the method itself, the results of laser scanning, methods for determining the displacement parameters from laser scanning data are given.
