The impact of nanostructures on the nanochemical and microbiological iron-oxide-silicate ore materials (IOSOM) transformation processes is studied using physicochemical, microbiological and physicochemical geomechanical methods, and their correlation with subsequent processes of separation, purification and enrichment of these materials is shown. Nanostructure limiting impact on all stages of sequential processes of the natural and technogeneous IOSOM transformations is noted. Based on obtained results, a scientific substantiation of the developed methods of IOSOM processing and purification from aluminosilicates, arsenic, phosphorus and sulphur impurities is given, and recommendations for their improvement are given too. Practical implementation of environmentally safe and waste-free developed methods allows fabrication of highly enriched (up to 90–95%) magnetite and metallic concentrates from the poor IOSOM.
