Аннотация: The paper describes the studies of processing tails of the Olimpiada Mining and Processing Complex with the methods of chemical, mineralogical, electronic microscope, deep reductive melting with division of the melt into a silicate and metal parts. It is demonstrated that 85% of the processing tails consist of the oxides: SiO2, CaOПоказать полностью, Al2O3, Fe2O3, H2O and CO2. The distribution of gold and silver is provided by the size classes of the initial blend, after melting of which in reduction conditions re-distribution of gold to the metal phase of the melt occurs. The silicate part of the melt when released into water in the "thermal shock" mode forms a light porous X-ray amorphous material "foam silicate", which also serves as a resource for stable chemical composition for production of a wide range of import substituting ceramic materials.
