Rational design of low-tonnage technological complexes for fine and ultrafine grinding of materials

Based on the study of ways to increase the efficiency of metal production through the use of technologies for leaching substandard ores in terms of metal content, a data bank was formed and an algorithm for controlling the processes of leaching substandard non-ferrous ores in terms of metal content was proposed. The concept of the development of technogenic deposits by leaching metals is proposed as an important direction of rational use of subsurface resources. The development of an algorithm for controlling the process of leaching non-ferrous metals from substandard raw materials is a tool for compensating losses of valuable and scarce raw materials allowed in the technological chain. Aspects of the mechanochemical technology of extracting metals to obtain an ecological and economic effect and radical hardening of the mineral and raw material base of mining have been studied.

“…Rising prices for non-ferrous and rare metals stimulate the use of tailings mining and processing of ores [24,25]. So, in Bohemia, useful components have been extracted from old dumps since the 80s of the last century.…”

The information about the state of the use of natural resources in Russia is given and the need to search for new sources of raw materials for industry is justified. There is a tendency to reduce the production capacity and the rate of extraction of metal ores, which does not allow the use of the infrastructure of mining enterprises and creates the problem of processing substandard ore deposits and disposal of accumulated waste. The concept of deep processing of substandard metal-containing raw materials and a strategy for the survival of mining enterprises, including the use of metal leaching technologies, is formulated. The advantages of technologies with the leaching of metals from mineral raw materials at the stages of its processing are characterized. The advantages of leaching in disintegrators are shown by comparison with the indicators of the basic variant. It is noted that mechanochemical activation improves the quality of concretes made on the basis of recycled tailings. Managing the properties of recyclable materials allows you to implement the principles of resource conservation with an economic effect. It is concluded that the recommended technology is the real direction of technological modification of production.

An increase in the extraction of resources is accompanied by their losses and dilution of ores due to the technogenic impact on ore-bearing massifs. The possibility of preserving the earth’s surface is provided by technologies with filling technological voids with hardening mixtures based on leach tailings, the insufficient activity of which is increased by processing in disintegrators under the influence of high energy. Experimental proof of the possibility of controlling the state of the hardening mixture was obtained in the course of many years of use of the disintegrator as part of the filling complex. The possibility of replacing cement with activated tailings has been proven not only as inert fillers but also as binders, which makes it possible to replace commercial cement with cheaper production of commercial products. Utilization of metals from enrichment tailings of various types of minerals allows the use of secondary tailings without restrictions on sanitary requirements. The combined effect of mechanical and chemical energies allows waste-free disposal of enrichment tailings and creates, in essence, a new base of metal raw materials to meet the needs of industry.
