Biotesting as a Method of Evaluating Waste Hazard in Metallic Mineral Mining

摘要

As the result of identifying content of each chemical element it has been revealed that metallic mineral wastes have a considerable amount of valuable useful metals. Thus, large-tonnage inorganic wastes are considered to be an additional raw source of metal production. This paper highlights the necessity of supplementary biotesting metallic mineral wastes in order to bring into correlation with corresponding hazard classes and facilitate efficient recycling of these wastes in future. It has been found out that determined in this way waste class can be dumped or used after recycling. It has been also indicated that mill tailings are to be stored according to contained metals without messing up dissimilar metal-containing wastes. After winning metals these wastes are similar to the group of inorganic non-metallic wastes and can be used in building material production, for filling mined-out spaces, in road construction etc.
