FIELD : metallurgy.SUBSTANCE : invention relates to hydraulic metallurgy and may find application in technology for extraction of non-ferrous, rare, precious and radioactive metals from ore stock using ions of trivalent iron as an oxidiser, and also for cleaning of acid solutions from iron in hydrometallurgical industry. The plant comprises a neutron accelerator and a reaction chamber with a return solution, a mixing device, a temperature sensor, an automatic control and monitoring system. The plant is also equipped with a heat exchanger with liquid cooling, a box to monitor concentration of a radiated solution, an accumulating tank with an overflow pipe, a circulating pump and a recirculation system joined with the reaction chamber into a closed circuit, along which the return solution circulates. The reaction chamber is equipped with an inlet window with a separating diaphragm and a cylindrical cartridge arranged with a nozzle for supply of return solution and installed coaxially in its active zone.EFFECT : invention provides for continuous regeneration of an oxidiser in process of leaching, higher yield of metals, efficiency and productivity of metals extraction from ores.5 cl, 3 dwg
