METHOD OF HEAP LEACHING OF METALS AT SUBZERO AMBIENT TEMPERATURE Russian patent published in 1997 - IPC

Abstract RU 2091573 C1

FIELD: mining industry; applicable in heap leaching of metal ores. SUBSTANCE: the offered method includes formation of impervious base, laying of pile of metal ores subject to leaching, supply of reagent solutions to pile and collection of productive solutions. Novelty consists in that at subzero ambient temperature, supplied to pile are reagents which ensure dissolving of metals in form of ions with lowest valency. EFFECT: higher efficiency. 1 dwg
