New Methods of Mineral Processing and Technology for the Progress of Sustainability in Complex Mineral Raw Treatment

"The ores of black, non-ferrous, rare, noble metals are mostly distinguished by a variety of mineral types and complexity of their material composition.The article is devoted to the promotion of the concept of mineral processing in modern realitiesof the deficit of high-quality ores and increase their demand.Normative and methodical documentationsfor specific types of analysis with the definition of the field of application are shown. For example,the pyrochlore-monazite-goethite ores from one of the deposits from Eastern Siberia - Chuktukonskoe ore fieldare tested. The development of mineralogical methods, and testing of specific raw materials are shown.The method of small-angle X-ray (and also synchrotron) scattering, which was developed for solving problems associated with structural high-resolution diagnostics, was tested for bauxites of Vezhay-Vorykvinskoye field. KEYWORDS Technological mineralogy, rebellious ores, ore quality assessment, ?mineralogical-analytical methods INTRODUCTION A highly intense production of many types of mineral raw results in gradual depletion and deterioration of mining-geological and mining-technical conditions of development. Relatively easily accessible and rich deposits are getting exhausted in the first place, and it is necessary to involve poor and rebellious ores into production and processing. Traditional technologies can hardly be applied (Chanturia, 2017; Bazin et al., 2014; Ponaryadov, 2017). The urgency of development of the concept of technological mineralogy focuses on the confirmation of new methods and approaches to the development of mineral raw, creation of scientific and methodological prerequisites for solving the problem of rational development of mineral raw, maximal extraction and integrated application of all minerals (both principal and associated), expansion and strengthening of mineral and raw base. The article is aimed at updating tasks that should be addressed within the applied mineralogical researches: – the forecast of quality of ore at early stages of exploration and technological indicators for the redistribution of raw, – interactive monitoring of these indicators by mineralogical and analytical methods; – assessment of environmental consequences of mining and processing of minerals and measures that eliminate these consequences."
