Innovative approaches to the management of mining waste in South Ural

The aggravation of the ecological and economic situation in the areas of mining and processing of ferrous and non-ferrous metals in the South Urals requires the development of new approaches to recycling and prospects for the future processing of mining waste. We discussed criteria that determined the type of technogenic massif formed - syngenetic or epigenetic on the basis of complete information about the processes of mineral formation, material composition and morphostructural features of the mineral phases that formed the technical stone. The subject of the study was the sample of stowage with the age of hardening of 180 days, the components of the filling mixture - granulated blast furnace slag of PJSC MMK, the tailings of the enrichment of copper-plated ores of the Gaisk concentrator. Using a complex of mineral-analytical methods - optical microscopy (optical-petrographic and minerographic), x-ray and thermal methods - allowed the authors to assess the morphological features of the constituent components of the stowage, the chemical composition, the newly formed mineral phases and characterize the technogenic massif formed from the stowage as epigenetic.
