GOLD EXTRACTION FROM ORES AND CONCENTRATES Russian patent published in 2014 - IPC C22B11/08

Abstract RU 2522921 C1

FIELD: metallurgy.

SUBSTANCE: proposed method comprises loading initial ground stock into reactor and its processing by cyanide solution with pulp circulation and dispersion by compressed air. Note here that pulp processing involves application two-beam opposite hydroacoustic radiator with opposite fan-shaped radiation of wide-band continuous-spectrum acoustic oscillations and fan-shaped spray of air micro bubble clouds inside the reactor, air being active sucked in rarefaction zone developed by said radiator.

EFFECT: high-intensity extraction.
