Kubak D.A., Petuchov V.N., Semenov D.G. The investigation of the effect of complex reagents sectional chemical composition on coal flotation efficiency

Abstract

Flotation activity of complex reagents was investigated on the coals of different stage of metamorphism. It is rationally to use reagents containing polar organic compounds in the sectional chemical composition for coals related to the low degree of metamorphism. Coals, having the higher degree of metamorphism, differing by reduced content of functional bunching and greater porosity on the surface, are better floated by complex reagents with a number of non-polar organic compounds. Reagent RNH-3010 predominantly consists of polar oxygen-containing organic compounds. To improve the collective properties of the complex reagent RNH-3010 petrochemical industry waste, containing different non-polar organic compounds, were investigated. Among the examined waste additive DRIPB is recommended, allowing to increase the technical and economic indicators of the process. Optimum ratio of polar and non-polar components is defined. High and low content of non-polar part leads to the indicators deterioration of froth flotation. Technological process indi-cators of froth flotation, allowing to receive a concentrate, that meets the requirements of coke-chemical production. Granulometric composition and pulp density have a significant impact on the performance of froth flotation. Advantages of the proposed reagent conditions are low cost, significant resources and high efficiency in comparison with its analogues.
