FIELD: mining industry.
SUBSTANCE: method includes removal of melted soil from portion meant for forming of stack, placing of anti-filtering base, mounting equipment for draining productive solution, placing of lixiviated rocks at base of stack and feeding of reagents solution into the stack. Into stack of melted freezing or frozen melting or frozen clotted or frozen broken by freeze cracks rocks solution of reagents is fed, into which light-soluble salts of univalent metals are injected with low eutectics temperature, which do not engage in reactions with working reagents and possible intermediate products of chemical reactions, up to concentration, close to saturation, and by this melted lixiviated rocks are prevented from re-freezing, and frozen rocks are melted and in such a way lixiviation process is provided for up to its finishing stage during whole year.
EFFECT: possible lixiviation during whole year, simple and efficient operation.
