FIELD: metallurgy. ^ SUBSTANCE: group of inventions refers to method of metal extraction from ores and device for method implementation. Method involves leaching by leaching solution with oxidiser, along with radiation of leaching solution by accelerated electrons of 50 keV to 1.7 MeV energy with rate adjustment for flow fed to leaching. Further metal is extracted from solution, and oxidiser is recovered in solution and recycled in leaching process. Device for metal extraction from ore includes vessel with leaching solution, vessel for leaching, chute connecting vessel with leaching solution and vessel for leaching, height adjustment unit for vessel with leaching solution, solution feed and drainage systems, and electron accelerator. The chute is used for transportation of leaching solution through electron accelerator zone, and height adjustment unit for vessel with leaching solution is used for leaching solution flow rate control. ^ EFFECT: intensified metal leaching from ores, reduced amount of chemical reactants and power consumption. ^ 2 cl, 1 dwg, 3 ex |
