| description | Relevance. As the enrichment does not allow achieving full disclosure of minerals, they are improved due to additional mechanical operations and chemical processing, which significantly increases the extraction efficiency. Therefore, the direction is relevant due to utilization of large amounts of substandard raw materials by leaching metals. The aim of the study is to develop the concept of mechanochemical leaching of wastes of mining and processing ores. Research methods: critical analysis of best practices in development of similar deposits on publications, laboratory studies of processes in disintegrating install. Object of the study: the combined leaching of metals from waste products using chemical reagents in the cage. The results of the study. The concept of extraction of metals is specified by the method of mechanochemical activation. It is confirmed that the mechanochemical activation allows not only extracting valuable components from waste, but also bringing them up to the required standards. The authors offered the ecological mathematical model for the effective assessing the extraction of ferrous and non-ferrous metals from waste of ores enrichment. The indicators of metal extraction from tailings of metal ores were ascertained. The technology of recycling ore enrichment allowing us to reduce the volume of storages of tails with receiving economic effect is recommended. The paper introduces the method of expanding the mineral resource base of the enterprises by production of raw materials. Conclusions. The extraction of metals to the level of unlimited use by traditional methods is impossible and has the prospects of improvement when combined with chemical technologies. Wasteless extraction of metals is possible with the use of high activation energy in such devices as the disintegrator. The practical use of mechanochemical technology to extract metals from open tailings is a reserve for expanding the raw materials base and recovery of metals production. |
