Abstract. The article deals with the problem of pollution of rivers with quarry and mine waters, as well as with excess tailings water in the conditions of the Krivoy Rog iron ore basin. It is shown that, in spite of the measures taken to flush the Ingulets river, the quality of water in control areas, after discharging the settled mine waters and tailings water into the river, is unsatisfactory and leads to salinization and degradation of agricultural lands, which are irrigated by the waters of the Ingulets river. The desalination methods for saline water were analyzed, and the results show that the most progressive methods are those, which are based on the use of desalination plants operating on renewable energy sources with molecular filtration of solutions. It is proposed to perform desalination of quarry and mine waters, bringing them to the condition of drinking water supply, which will save natural sources of fresh water, prevent their pollution, give additional water resources, and improve the river state and preserve quality of soils. At the same time, in order to achieve economic efficiency, it is proposed to use nonvolatile desalination plants operating on renewable energy sources. The directions of storage advancement and use of brines formed during water desalination are proposed.

Keywords: highly mineralized mine and quarry waters, desalination plants, concentrated brines, mining of minerals, ecologically oriented production cycle.
