| 摘要 |
FIELD: mining industry. SUBSTANCE: ore is preliminarily acidified with acid solution and then precious metals are leached with 0.01-0.2% aqueous solution of chlorine at ratio of molecular chlorine to hypochlorous acid more than 1. Chlorine is fed such as to provide in product solution pH <5, and electrostatic potential above 650 mV. EFFECT: enhanced recovery efficiency.
