FIELD: mining.
SUBSTANCE: method of underground leaching of ores of deposits on geochemical oxidising-reducing barriers involves construction of geo-production wells, preparation on brine water of a leaching solution, its supply to injection wells and removal of product solutions from extraction wells. At preparation of a leaching solution, concentration of at least three substances contained in brine water is increased; quantitative relationships between them are maintained as equal to their ratio in brine water; content of these substances and relationship between them is determined as per water samples taken from an oxidised part of an oxidising-reducing barrier.
EFFECT: improving leaching efficiency.
