Abstract: The place of Russia in the global iron ore production is determined. The practice of the underground method for iron ore deposit development in Russia and the CMA is described. The shortcomings of the existing concept for non-waste mining and processing production based on the use of concentrator tailings as a slurry to fill the depleted cells. It is proposed to use the technology mechanical activation in disintegrator type plants for the extraction of metals and residual the revealing of mine refuse viscosity properties.
