Abstract
The paper presents studies of technological parameters of coal concentrate with ash content of 9.6%, obtained from flotation wastes of Krasnobrodskaya-Koksovaya coal preparation plant. By methods of technological mineralogy, the characteristics of the mineral component of coal, which directly affect the ash content of coal concentrate are studied: composition, distribution by size and density classes. The main coal properties have been determined: analytical moisture, carbon content, ash content, volatile matter yield, higher heat of combustion, total sulphur content and petrographic characteristics. An attempt was made to relate coal concentrate obtained from flotation tailings to the available quality standards for coal products.
Keywords
