Two approaches have been proposed to analyze the quality of the slag: metallurgical evaluation of and environmental impact assessment. The analysis of the metallurgical quality of the slag using the DTA methods was carried. In the paper a method of determining the reduction capability of slag solutions was used. There are the oxides complexes used in to the slag composition for the purpose to establish two quality indicators in reduction processes: EW - indicator showing the direction and intensity of reaction in to the slag composition and r - indicator of the rate of coal consumption. Proposed to other qualitative criteria. The analysis was conducted on the example of slag from aluminium metallurgical processes, and slag from the smelting processes of copper and its alloys. Divided influence on the environment and the use slag in other processes. Discusses the quality of the slag as a function of their operating qualities. Highlighted the need qualitative assessment of slag in a broad sense. Indicated the necessity to analysis including the quality of the slag more criteria, including: - technology - suitability for further processes, - operational, environmental and economic benefits.
