FIELD: hydrometallurgy of noble metals; applicable in gold recovery by leaching the concentrates of ore gravitation concentration. SUBSTANCE: device for leaching of gold-containing granular materials has body with inlets and outlets of solutions, inlets and outlets of materials. Body is additionally equipped with a solution flow divider which is located in the lower part in form of bed from inert granulated material with density of 7-12 g/cu.cm and sand gate formed by solution inlets and outlets installed inside the body along its axis. In this case, inlet of solutions is installed with a gap from the top below the bed level, and outlet of solutions is installed inside the inlet of solutions over the level of bed. EFFECT: reduced losses of dissolved valuable components with cakes and consumption of reagents in subsequent processing of solutions due to efficient washing out of the leached material, and increased reliability of device operation. |
