The article describes a technology for valuable components extracting from the man-made waste storages at the Krivbass ore-dressing and processing enterprises which are considered as promising man-made placers. Two approaches to such placers developing are considered which assume valuable component extraction both after closing and in process of operation of the waste storages. It is shown that implementation of practice of valuable components co-extraction from areas between dam and pond in conjunction with technology of combined waste storing requires changing of technological scheme in the maps of inwash district, and, to this end, it is rational to combine several operations. Technological parameters of the co-extraction from the man-made placers by means of hydromechanical facilities were grounded. The required performance of hydrotransport facilities needed for delivering tailings to the current inwash horizon and concentration of the discharged pulp were specified.
