Special role of nanoscience and nanotechnology initiatives in improvement of processing, enrichment, and purification of iron ore raw materials (IORM), in particular, iron oxide silicate sedimentary materials (IOSSM) containing impurities of phosphorus and other elements is shown. Colloid-chemical and nanochemical concepts on iron ore nanoparticles’ role in carbonization processes of IORM and IOSSM, followed by direct reduction of iron oxides contained therein into metallic phase, are considered. Their role in processes of alkaline purification and separating of iron-containing phase from phosphorus compounds and other impurities are also developed. Wasteless solid-phase processing method as well as the methods of enrichment and purification of IORM and IOSSM from phosphorus, silica, and other impurities are developed using obtained results. These methods exceed known methods of iron direct reduction and its purification.

Key words: solid-phase reduction, iron, alkaline purification, nanochemistry.
