FIELD: mining. SUBSTANCE: method includes formation of impervious base, laying of slack of rocks to be leached and supply to stack of reagent solutions. During warm year period of time, removed from area designed for stack location is thaw ground down to frozen ground and disposed beyond boundaries of said area. Cup-shaped hollow is formed in frozen ground. Equipment for transfer of producing solution is installed at lower point of said hollow. Leaching is started after formation of stack above said hollow before cold time of the year. Producing solution is pumped out until maximum freezing of stack or completion of leaching process. EFFECT: prolongation of leaching process in winter time, simplified method and ecological cleanness of leaching. 1 dwg
