Technology for Nonwaste Recovery of Tailings of the Mizur Mining and Processing Plant

The state of usage of natural resources in Russia is described, and the need to search for new sources of metal-containing raw materials for the industry is substantiated. There is a downward trend in the ore mining rate, which confirms the expediency of processing substandard ores and disposing accumulated waste. A strategy for restoring the lost potential including the use of metal-leaching technologies is formulated. The advantages of such technologies are characterized. It is pointed out that most of the ore processing waste can be used in production. The results of experiments on brining non-extracted metals into solution are presented. The advantages of leaching in disintegrator mills are shown by comparison with the reference case. Changing the quality of recycled mill tailings makes it possible to implement the principles of resource saving for gaining economic benefits. It is concluded that the recommended technology shows a way of technological diversification of production, tailings can be a cheap and affordable raw material for related industries, and the mechanochemical activation of the leaching process in a disintegrator ensures the recovery of metals from the mill tailings of Sadon polymetallic ores. Quantitative strength characteristics of the hardening mixture as a result of activation by alternative methods are obtained. It is established that the strength of concretes based on activated mill tailings increases.
