METHOD OF METALS HEAP LEACHING Russian patent published in 2002 - IPC

Abstract RU 2186207 C2

FIELD: mining. SUBSTANCE: method includes formation of impervious base and rock heap subject to leaching. Before approaching of subzero temperatures of environment, rocks are moistened up to full moisture capacity. With approaching of cold season, heap is blanketed by covering with snow. During spring, rate of thawing is increased to increase coefficient of filtration due to formation of voids in rock during its spring thawing, by snow removal with the help of its darkening by application of particles of dark powder to snow. EFFECT: increased efficiency of filtration of rocks, accelerated process of leaching.
