ABOUT A POSSIBILITY OF PROCESSING OF TECHNOGENIC WASTE WITH USE OF THE NEW EQUIPMENT AND FLOTOREAGENT
Abstract
At present, there are tendencies in the world of depletion of ores and the involvement of low-grade and technogenic raw materials into processing. The ever-increasing scale of industrial production, with the involvement of valuable raw materials components in the processing of raw materials, led to an increase in the amount of man-made waste polluting the environment. Hundreds of millions of tons of flotation tailings accumulated in the tailings processing plants processing various ores, which contain significant quantities of non-ferrous and precious metals, the content of which exceeds the content of metals in the currently mined ore. In conditions of a significant depletion of balance reserves of various ores and a decrease in their quality, the waste of enrichment can be considered as an additional source of metals. The large losses of non-ferrous metals in the studied technogenic and mineral raw materials are associated with the very fine dispersion of useful minerals, their close interdependence between themselves and rock-forming minerals. The possibility for flotation tailings processing by using combined collector and generator air-water microemulsion. A combined collector is a mixture of composite Aeroflot, thionocarbamates TS-1000 and butyl xanthate with reactants ratios 1:1:3. The proposed technology using combined reagents and air microbubbles produced by the air-water microemulsion generator will improve the flotation of low-quality and technogenic raw materials containing non-ferrous metals. When used together, the combination of the collector and generator air-water microemulsion in comparison with the basic mode, the lead content in the rough lead concentrate increased by 7.1% and the extraction пїЅ increases by 5.83 %. The content zinc in the rough zinc concentrate increases by 3.8 % and the extraction to 14.13 %. Consumption of modified reagent in comparison with basic collector to reduction by 15 - 20%.
