| Popis: | The blast furnace and basic oxygen furnace route of steel making (from iron ores and coke to steel) or the so called integrated steel production generates simultaneously solid waste products. The slag is predominant, consisting of blast furnace (BF) slag and basic oxygen furnace (BOF) slag. The major share of this has been stored with no control near industrial area forming a metallurgical waste dump. For solving the problems of metallurgical residues and wastes stored in the old dump, the authority develops an appropriate environment policy for a proper management. The landfilled slag is exploited under supervision. The paper presents the sustainable recycling solutions applied in correlation with the properties of old slags. The performance of recycling solutions for each slag type is discussed according to the chemical composition and structure. Specific cooling conditions (as well as the chemical composition) of slag dumped under the action of variable weather conditions are analysed. |
