FIELD: mining.
SUBSTANCE: invention relates to the mining and can be used in heap leaching of rare, radioactive and noble metals from ores, tails and concentrates. The basement of the stack for the ore heap leaching consists of the ore stack, supplying collector for leaching solution, stack sprinkling system, upper protecting drain layer, hydroisolating layer of polyethylene film, upper electrode (cathode) mesh, lower electrode (anode) mesh, lower protecting drain layer, gathering collector for leaching solution, ground mud screen. The technical outcome of the invention is that the safety of the basement is increased due to the electrochemical oxidation (destruction) of cyanides and their complexes at local tear of polyethylene-filmed hydroisolating layer.
EFFECT: safety of basement of stack for ore heap leaching is increased.
