METHOD FOR LIXIVIATION OF METALS FROM HARD-TO-PENETRATE ORES WITH HIGH CONTENT OF CLAY Russian patent published in 1997 - IPC

Abstract RU 2083814 C1

FIELD: geological technology. SUBSTANCE: method can be used at grouped lixiviation of metals and it implies formation of antifiltration base. Pile of rock to be lixiviated is built on antifiltration base, and solutions of lixiviating reagents are delivered into rock mass through perforated pipeline for dissolving metals out of rock mass. Added into delivered solutions is metal to be lixiviated and its salts. EFFECT: high efficiency. 1 cl, 1 dwg
