The results of the research into sifting of eastern Donbass gob pile processing as raw material for manufacturing wall ceramics, that is popular industrial raw material of the region, are highlighted in the report. It is stated that the main sifting components are siltstones, clay slates, claystone, and sandstones. The main minerals of the sifting are feldspar, crystalline silica, mica, and hydromica. The haracteristic of sifting handling ability for which the most suitable is the way of goods compression molding at elevated pressure and reduced humidity is given. It is stated that the main technology factors are grain composition of raw material mass, its humidity, compression pressure and firing temperature. Variation of technology factors' data makes it possible to get different kinds of products (course, lining, arch brick) with a wide range of features. Methods of evaluation of quality merit rating and the way this rating affects properties of final product are offered. There is high economical perspective of sifting implementation for production of wall ceramics. Currently, active processing of the refuse heap is taking place in the coal-mining districts of Rostov region (Eastern Donbass). It is mainly being done for the purpose of coal extraction which lately has become economically reasonable. Some secondary elements are being extracted while processing apart from coal. These elements are classified by grain size composition. Fractions 0-0,5 and 0-2 mm, containing coal at the rate of 15-50 %, are used as fuel adding during the production of ceramic bricks and as low energy [1-3]. The material with the size ranging from 4-6 mm to 80-90 mm is broken up and is implemented as broken stone in building. Fraction 2-6 mm, that hardly contains any coal and is called sifting, is the list popular for some reasons. General sifting supplies in Rostov region make up several millions of tons and continue to grow. All Eastern Donbass gob piles are divided by the prevailing kind of composing rocks to three groups: – made up by claystone and clay slate; – made up by siltstones and sandstones; – of mixed composition, made up by claystone, clay slate, siltstones and sandstones. * Corresponding author: Khungianos@mail.ru
