| Abstract | The potential of geothermal resources of Ukraine for mineral substances extraction has been analysed within this article. There have been offered complex use of power, mineral and water constituents of geothermal transmitters. As for the deposits located on the Crimean peninsula the technology of iodine extraction from geothermal waters has been suggested. This technology combines adsorption and diaphragm methods. Sorbent series have been researched and based on modified silica gel sorbents efficiency use has been showed. Ukrainian deposits of geothermal waters contain considerable power potential (thermal energy as well as dissolved combustible gas) and mineral constituents. They are concentrated in four artesian basins: Zakarpatsky, Prikarpatsky, Dneprovsko-Donetsky and Prichernomorsky. The confirmed resources of geothermal waters make up more than 27 million m3 per day with a temperature about 70° C. Mineral composition of Ukrainian geothermal waters (mean values of general mineralization within the limits of 30-350 g/dm3) is represented mainly by the ordinary set of sulphates, chlorides and carbonate metals. Deposits of geothermal waters containing iodine (25-35 mg/dm3), bromine (85-90 mg/dm3), boron (60-65 mg/dm3), strontium (300-350 mg/dm3), rubidium (to 5 mg/dm3) and lithium (to 10 mg/dm3) are perspective and promising for industrial production. The main task for industrial production organization of the above listed substances is the development of technologies and technical projects aimed at complex use of the whole spectrum of geothermal carrier constituents. Above all the projects provide for power support of technological cycle due to own geothermal water thermal energy and dissolved gas use. |
