The mineral sector as the state's backbone?
The author describes the current situation in the country's mineral sector and notes that it faces a number of problems of organizational, technological and legislative nature. He underlines that the orientation towards raw materials' export thwarts the development of the Russian economy and subordinates it to the situation in the international market. The author suggests specific measures aimed at improving the condition of the mineral resources base as the basis of the nation's mineral resource security.

Researching and validating the processes of precious metals extraction from placer sands using flotation methods
The authors demonstrate that chemical agglomeration in a centrifugal field is an efficient method for extracting finegrained gold from placer deposits. They have found that the use of a sorption media (oak saw dust) with the flotation method of enrichment facilitates increasing the precious metals yield. The use of physico-chemical and flotation methods during the extraction of fine-grained gold allows cost-effectively engaging the by-product sands of placer deposits in the processing.

Economic performance analysis under different scenarios of mining operations during the development of minor copper-sulphide deposits
The author considers four scenarios of minor deposits development: sequential, sequential-parallel, parallel-sequential and parallel. The analysis of dependence shows that the sequential development scenario ensures the highest yield index with the smallest discounted costs.

High-angle hoist for conveyance of rough mined rock from deep mines
In order to deliver mined rock (including large-sized) from the bottom of deep mines to the surface, the author suggests using a carrying apron construction which allows to prevent displacement and cascading of rock during its transportation. The proposed construction was designed at Kunaev Institute of Mining.

Model practical guidelines for assessment, rationing, accounting and economic evaluation of mining losses of solid minerals with respect to the new economic environment
The model practical guidelines for assessment, norming, accounting and economic evaluation of losses of solid minerals during the production adopted by State Committee for Mining and Industrial Supervision of the Soviet Union in March 1972 are still in place. These guidelines should be subject to amendments and addenda proposed by the author and determined by the new economic system, especially in respect to the feasibility study of the rational level of mining losses with regard to the enrichment process. Setting forth the proposals concerning the amendments, the author basically boils them down to the system of natural and economic indicators which determine the essence of the problem as applied to the processes of solid minerals extraction and the mineral raw materials processing.

Reduction of anhydrite losses due to optimization of the rib pillar sizes
The authors dwell on the issues of reducing the mineral product losses in rib pillars when mining non-metallic deposits using the board-and-pillar mining method. The works have been carried out at Gorozubovskoye anhydrite deposit. Based on the findings the authors propose a method for determining the rib pillar width.

Development of conception of brining of poor and non-saleable ores of the Republic of Kazakhstan to a commercial level
The author substantiates the concept of development of the mineral resources base of the Republic of Kazakhstan by means of developing the medium and small mineral deposits and by-product mineral resources. Using the case study of iron-ore deposits he demonstrates the possibility of ensuring the steady operation of ore mining and dressing plants built at medium-size deposits by means of supplying the ore from adjacent small deposits. The author also analyses the experience of operating modular dressing plants and production of ore concentrate merchantable in the world market.

On statutory regulation of insurance activities in the Russian Federation as applied to the subsoil resources management
The authors demonstrate some specifics of the insurance activities in the Russian Federation in the course of the subsoil resources management. They provide the list of insurable events and specify which types of insurance must be obligatory and which ones should be voluntary. The authors prove that the insurance premium rate depends on many different natural, climatic, geographical, morphological, mining-and-geological, technical and technological factors and insurance terms. They also set forth the proposals concerning improvement of legislation governing the relationships in the sphere of insurance in subsoil resources management.

Preliminary results of trenched faults observation in the geodynamical testing ground
The authors set forth the results of high-precision levelling surveys carried out in a geodynamical testing ground used for injecting liquid toxic wastes into the underground horizons. They point out the leaps of the ground elevation reference points of the profile lines crossing the geological fault. They also provide the preliminary conclusions concerning the reasons of this phenomenon.

Upgrading the close JSC «Karabashmed's» copper-smelting plant and the dynamics of the natural environment changes in the affected area
The authors describe the current state of the natural environment in the areas surrounding Karabash copper-smelting enterprise in the Urals, which is recognized as a facility producing very strong adverse impact. In consequence of the atmosphere pollution and industrial effluents the concentration of hazardous substances in soil and water bodies in the town of Karabash and the adjacent areas are considerably higher than the established maximum permissible concentrations. In 2001-2005, a large-scale environmental project was implemented aimed at retooling and modernization of the copper smelting production. The result was considerable reduction of pollutant emission. However, the problem of the natural environment pollution was not completely resolved.
