摘要：The research in the field of waste treatment technologies especially heavy concrete. A valuable component of especially heavy concrete waste is iron ore of granules. The article suggests the extraction of material using the technology of dry magnetic enrichment of the ore. Research conducted aimed at finding the optimal method of processing and recycling of heavyweight concrete wastes. The resulting secondary material was studied. The preservation of relatively high strength and guarantee characteristics is revealed, which allows reusing it in the production of heavy concrete without loss of quality, as an additive to the initial mixture. To implement the project on an industrial scale, calculations to select devices and constitute a process flow scheme. The issue of recycling of accumulated and newly formed wastes of production of especially heavy concrete is being solved, as well as reduction of payments for placing them in landfills.
