FIELD: mining industry.
SUBSTANCE: method includes removal of soil from portion, meant for construction of stack of rocks for metals lixiviation, forming of anti-filtering base, mounting equipment for draining productive solution, placing lixiviated rocks on prepared base and feeding working reagents solutions into stack. In base of frozen rocks stack metallic net is placed, above it a layer of roughly broken rocks with thickness equal to fractions of meter, above it a rough fiber is placed in one or several layers, in same layer horizontal perforated polymer pipes are placed, not pressed by higher rocks, for feeding solution of working reagents and admixtures. Then stack is subjected to effect of UHF electromagnetic field of generator plant, displaced along upper stack surface by shuttle method for its even heating. Hot solution of working reagents and admixtures is fed into layer of rocks under pressure along perforated pipes with increase of melted working zone and displacement of melting front upwards, until finishing process of metals lixiviation from the stack.
EFFECT: higher efficiency.
