INRTU scientists offer technologies on complex treatment of ground mineralized waters

Specialists of INRTU Department of Mineral Processing and Environment Protection offer the technologies on desalination of ground waters with a high level of mineralization. According to the scientists, the technologies will contribute to environmental problem solving and will allow extracting salts from solutions for industrial production.

Professor of INRTU Department of Mineral Processing and Environment Protection Elena ZELINSKAIA told that there is a big volume of ground waters on the territory of Siberia. Fresh water as well as solutions with high density of micro and macro components – salts, so called brines could be found. Potable mineral water producers and health resorts actively use this potential. However only weakly mineralized water can be used for these purposes.

Mineral water resources with salt concentration up to 500 gram per liter are unclaimed. It is found by the development of deposits, fiery seam opening-out and oil-well drilling.

Once on ground surface, highly mineralized solutions exert a certain impact on the environment and lead to change of soil, landscape and congelation conditions. All this has a negative effect on the nature and represents a danger for mining enterprises.

To solve this problem INRTU scientists suggest demineralizing underground brines. Three methods such as freezing, sorption and flotation will be suitable for desalination. All these technologies mean salt extraction for metal mining by liquid melt method.

Up to date natural waters of Siberia contain large amount of salts of cesium, rubidium, strontium and especially increasing in price lithium, which is irreplaceable in industry, starting from battery manufacturing ending aircraft designing.

Elena ZELINSKAIA notes that INRTU Department of Mineral Processing and Environment Protection is ready to cooperate with scientific organizations and industrial enterprises of Russia for the purpose of full-scale approbation of these technologies. According to Elena ZELINSKAIA, these technologies of desalination could be applied at Korshunovsky ore-dressing and processing enterprise (Nizhneilimsk district) specializing in ore extraction and iron-ore concentrate production. In addition, impressive resources of ground mineralized waters are concentrated in Kovykta gas field and several adamantine deposits of Republic of Sakha.

It should be noted that ground water desalination enterprises are opened in China. The concept of complex treatment of water resource is not applied in Russia which has large resources of highly mineralized waters. INRTU scientists hope that joint efforts of representatives of science and industry will help to solve this problem, and thus will promote ecological safety and intense development of domestic industry.
