Raman Characteristics of Kuznetsk Basin Coal and Coal-Based Sorbents

Corrosion, aging, wear of the basic production assets of the of the Kuznetsk Basin coal industry enterprises lead to huge losses of natural resources and material supplies; labor costs being increased. Most failures, breakdowns, malfunctions at industrial facilities, except for cases of misuse, are caused by the above mentioned factors. Therefore, the primary task is to develop methods for protecting equipment from corrosion. In this paper, the measures to increase the longevity of polymer-silicate mastic protective coatings by studying and optimizing the group of internal properties of polymer-silicates that determine the properties of the coating as a whole are proposed.

Introduction. Iron and magnesium form a common lattice of the initial ore and its calcination products, which is the main obstacle limiting the widespread use of the ores of the Bakal group of deposits. Research aim is to develop the physicochemical foundations of the integrated processing of high-magnesia siderite ores using pyro- and hydrometallurgy methods. Research methodology is based on data analysis from thermogravimetry, X-ray and Mössbauer spectroscopy, and chromatography. The analysis made it possible to determine suitable conditions for heat treatment, leaching, chemical and phase composition, structure and properties of integrated processing products of high-magnesia iron ore raw materials. Results. A new scheme for high-magnesia iron ore raw materials integrated processing has been proposed. Testing of the scheme in laboratory conditions has shown that it allows to increase the iron content in the concentrate by 7% and to obtain up to 100–120 kg per ton of highly active magnesia concentrate containing no less than 98% of magnesium oxide. It has been established that some products of the integrated processing are catalytically active in the processes of ethanol steam conversion and Kuznetsk Basin coal conversion, as well as in the water gas shift reaction. Summary. The proposed scheme makes it possible to increase iron and related elements extraction degree, without changing the working conditions on the operating plants.
