Abstract
The accumulated wastes in the dumps and sludge collector of metallurgical enterprises, including the preparation of raw materials (mining, agglomeration, al.), metallurgical and related industries can be used as raw materials in various industries, and, above all, in the steel industry. The reduction tendency of iron ore storage makes the processing of industrial waste particularly urgent for production of man-made iron ore. In the sludge collector of the West Siberian Steel Plant (OJSC “EVRAS ZSMK”) for more than 50 years waste from different industries have been stored: coal washing rock, ash from burning coal of power plants, sludge of gas cleaning systems of metallurgical units. In connection with the termination of operation of the sludge collector the development of technology for the processing of the accumulated technological waste is the urgent task. In order to assess the prospects of producing of iron concentrates from the main types of waste placed in the sludge collectors, a complex study of the mineral composition and crystal structure of iron-bearing minerals has been carried out using Mössbauer spectroscopy, X-ray diffraction, as well as chemical analysis and optical microscopy. It has been revealed that significant differences in the location of iron in the waste from various origins lead to the specifics of their elaboration technologies.
