This article presents qualitative and quantitative analysis of the waste produced by KGHM Polska Miedź. The waste has been analyzed according to its chemical composition and balanced in order to be reused and recycled. Special attention has been paid to mining industries producing the biggest amount of waste and ore enrichment businesses generating waste, which isn’t reused nowadays. Laboratory reseach has been conducted on floatation waste, different kinds of slags, waste gases and water slag extracts. Attention has been drawn to the possibility of using a computer program SLAG - PROP for analyzing physicochemical features, technological features and the refining of the acquired waste. Consequently, the further way of utilization of waste has been shown. From this point of view, analyses of DTA and TG slags in an oxide coating seem especially interesting. Having a particular composition they can be successfully utillised in the refining processes of copper pyrometallyrgy.
