摘要
FIELD: process engineering.;SUBSTANCE: invention relates to solution mining with the help of alkali or acid, particularly, to extraction of gold and other noble metals. Proposed method comprises activation of initial material y electric effects. Note here that said initial material is fed into chamber of electric effects. Note also that the latter are brought about by electrodes arranged in said chamber by voltage pulses applied thereto. Said voltage pulses feature the following parameters: pulse duration - 31 to 1000 mcs, preferably, 31-200 mcs, frequency - 21 Hz to 50 kHz, and amplitude approximating to 1000 V.;EFFECT: higher yield and faster process.;13 cl, 2 dwg
