Project summary

The purpose of the project consists in mining and analysis of the mechanism, processes and opportunity of technogeneous reproduction of mineral resources of lithosphere

The project is directed at the solving of geo-ecological problems of uranium mines of Kyrgyzstan after the completion of their performance. The kernel of the project consists in such technology at which radioactive mined rock deactivation takes place because of redistribution of the metals in the bulked massif, providing its subsequent useful recycling.

Traditionally increment of mineral raw resources of the various countries provided by search and discovery of new deposits of mineral resources (geologic reproduction of mineral resources). The opportunities of technogeneous reproduction of mineral resources made at the expense of redistribution of useful components in a mining massif or improvement of low initial quality of mineral raw materials on a place of its natural location, were not considered.

Now, owing to improvement of deposits of mineral resources with the most favorable mining-and-geological characteristics of burial and high quality of mineral raw materials, there is a significant deterioration of mineral raw base of global system. So, to the end of XIX century in USA accustomed to copper bearing deposit only with ores containing more of 5% Cu, and the mineral resources with the contents of copper in the first percents were considered non-commercial. In middle XX in copper ores with the contents Cu more than 1% began to be considered balance and were exposed to mining. Recently in Uzbekistan the copper- disseminated ore (deposit Almalyk) with the contents Cu<0,3 % are developed.

On the other hand, the deterioration of initial quality mastered natural (geogenic) of mineral resources causes formation of significant amount of wastes of a mining and processing, that results in strengthening negative influence on biosphere.

In case of realization of technogeneous of reproduction of mineral resources the arising resource crisis will be overcome and the negative action on biosphere is considerably reduced on the part of a mining complex.

A task of the project - to reproduce and to strengthen these natural processes.

If technology-induced renewing of mineral resources is fulfilled, the negative influence of mining complex decrease and emerging deficiency of mineral resources will be overcome.

Till now, the similar problem cannot be solved because of the absence of above mentioned ideology. With its appearance (applicants of the project are the authors of it), the necessary theoretical preconditions for the solution of the specified problems are occurring.

Project participants offer their own research development of ecologically sparing utilization of formerly radioactive rock because of redistribution of radioactive, nonferrous and precious metals in the bulked massif, causing the use of inert rocks in building industry, and radioactive anthropogenic ores - as mineral raw materials for hydrometallurgical plants.

Project participants have the necessary competence in studied area that is confirmed by their scientific qualification, scientific publications and 120 patents for inventions in studied area.

Upon project completion the following results will be obtained:

  • the mechanism of redistribution of the metals in the bulked massif will be developed;
  • the physical and chemical model of anthropogenic ore deposit will be created;
  • processes of leaching, migration and resedimentation (anthropogenic ore formation) of useful components in mined rock massif will be studied;
  • the most effective geochemical barriers for localization of useful components will be investigated;
  • the possibility of full liquidation of formerly stored mined rock of piles and tailing pits of uranium mines will be estimated and the appropriate technology will be developed.

On the basis of obtained theoretical and experimental data will appear a possibility of the quantitative description of parameters of the processes subsequently promoting in recycling of mined rock of piles and tailing pits formerly uranium-containing, as well as their optimum fulfillment terms that will permit to implement the specified technologies for useful application of such objects (up to their full liquidation and disassembling).

The project meets to such purpose of МNTC, as providing the scientists and experts related with the weapon, with theoretical justification of possibility of disassembling (development) mined rock of piles and tailing pits formerly uranium-containing, i.e. their recycling, because of preliminary redistribution of metals in rock massif with creation the areas of leaching (depletion) of metals and the areas of their sedimentation (concentration).

The methodology of researches under the project is based on possibility of disassembling and full liquidation of piles and tailing pits of uranium-mining industry because of purposeful redistribution of the metals in the bulked rock massif.

Technical approaches at the project implementation provide the experimental fulfillment of of leaching, migration and resedimentation of metals (U, Au, Pb, Zn), as well as computer physical and chemical modeling of these processes.

It is expected that the obtained results:
  • - can completely solve still available geo-ecological problems of suspended piles and tailing pits of uranium mines in Kyrgyzstan;
  • - will form a basis for development and application of similar technologies in other countries;
  • - will have the commercial potential and can become a basis for long-term business ties with all interested persons and entities;
  • - will permit to continue works on perfection of the nature protection and ecologically sparing technologies applied at uranium mines.

Leading experts on geo-ecology of mining manufactures (including uranium mines) - professor K. Drebenshtedt, professor B.Merkel, as well as professor H.Shrajbekh have kindly agreed to be collaborators of this project and actively participate both in discussion of scientific and technical results of possibility and technologies of recycling of uranium-containing mined rock of piles and tailing pits of uranium mines of Kyrgyzstan, and in rendering of consultations on selection and use of necessary laboratory experimental equipment for these purposes.
