FIELD: metallurgy.
SUBSTANCE: proposed plant comprises tank with processed material loading and unloading pipes, cyanide solution feed pump and circulation pump. It differs from designs in that it is equipped with at least one two-beam hydroacoustic radiator with fixed direction of acoustic field fitted inside said tank on its vertical axle and communicated with circulation pump inlet. Besides it has air feed pipe combined with cyanide solution feed pipe into common manifold. Outlets of said radiator are located at radiator rarefaction zone.
EFFECT: accelerated dissolution of gold and etching and higher yield.
