Prospects for Extraction of Useful Elements Out of the Brines of the Pre-Carpathian Downfold

extraction of potassium salts. The unique ratios of salt minerals
found within its deposits have no analogues in the world. And the
obtained, of their processing, high-quality products have always
been in high demand. However, the primary resources of the
largest deposits were almost depleted more than a decade ago, and
the formed post-mining territories became a source of
accumulation of negative environmental impacts. To cover the
current national demand and to increase Ukraine's competitiveness
in the world market, it is necessary to process secondary sources
containing salt components such as tailings, storage tanks, sludge
storage. A new approach and especially more efficient
technological procedures are needed for balancing economic and
environmental indicators and the brine processing of these
secondary sources. From an environmental and economic point of
view, membrane technologies use is considered to be more
appropriate than old brine evaporation systems. This work
investigates the possibilities of such processing regarding brines of
the Dombrowsky quarry of Kalush-Golinsky deposit. According to
the results, advantageous key financial indicators of the simulated
project were obtained. The results of the study are described with
respect to the possibility of implementing such an approach for
solving a set of environmental and economic tasks, such as
stabilizing the level of environmental security and increasing the
macroeconomic performance of the country.
