METHOD FOR UNDERGROUND LIXIVIATION OF METALS BY ELECTRIC CURRENT

摘要

FIELD: mining industry. SUBSTANCE: this relates to geotechnology and can be used for underground lixiviation of metals. Gold-bearing sands are exposed by drilling bore-holes. Bore-holes are provided with casing strings, filters, head-pieces, and electrodes. Used in lixiviation of gold-bearing sands is low-frequency electric current. Applied for lixiviation of gold-bearing clayey inclusions is high-frequency electric current. EFFECT: higher efficiency. 1 dwgi
