Abstract

Nowadays, accumulated volumes of Russian technogenic wastes in almost match the volume of mineral deposits, set on balance. The average level of industrial waste use in Russia makes up only 53%, while the percentage of production waste use as secondary raw materials does not exceed 11%. The percentage of industrial waste utilizing in Europe and in USA, makes up 85% and 95%, respectively. This article describes the classification of beneficiation methods for major technogenic raw materials of metallurgical industry. The offered beneficiation technology of slowly cooled slags of copper smelting production at Sredneuralsky Copper Smelter (UMMC-Holding) is an example of intensification of technogenic raw materials beneficiation processes. Research result is the significant increase of copper extraction from flowing slags at concentration plant. The study of the phase composition of slags shows the prospectivity of a slow slag cooling method due to recrystallization and transition of primary copper minerals to the secondary ones. The study of copper mineral release degree in flowing slags shows the mass fraction of released copper mineral grains in a flotation grade size of –0.071 mm, equal to 58.95%. Content of such grains with the same size in samples of slowly cooled slag is from 85.83% to 86.73%. The process flowsheet is given for the flotation size grade (–0.071 mm) and consists of three main, one scavenger and two recleaner flotation operations with aftergrinding of middling products. A reagent mode differed from a plant mode by decrease of slurry pH from 11–12 to 8–9. Industrial tests of an accumulated batch of slowly cooled slags at the Concentrating plant of Sredneuralsky Copper Smelter show the efficiency of such processing: extraction of copper into copper concentrate is increased by 15–19%, and decrease of copper content in tailings makes up 0.17%. The process figure effect enhancing is based on coarsening of valuable slag mineral grains and improving the phase analysis due to its slow cooling.
