Abstract
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.
Highlights
The amount of industrial wastes rises every year because of ore-dressing and processing enterprises
Processing plants majoring in iron ore dressing destroy Earth surface via mining, discharge air pollutants into atmosphere, dump contaminated wastewater and produce used fine-grained burden, that is, industrial wastes
Used materials are delivered by hydraulic conveying into tailing dumps
Summary
The amount of industrial wastes rises every year because of ore-dressing and processing enterprises. Extracted raw materials are delivered to processing plants affecting the environment negatively. Processing plants majoring in iron ore dressing destroy Earth surface via mining, discharge air pollutants into atmosphere, dump contaminated wastewater and produce used fine-grained burden, that is, industrial wastes. Used materials are delivered by hydraulic conveying into tailing dumps. Tailing dumps are aggregated wastes of ore-dressing and processing enterprises. Any waste operations produced as the result of mining, processing and storing mineral resources and opencast mine activities are legislatively regulated in Mining Waste Directive. In terms of up-to-date legislation [1, 3, 4] all industrial wastes are to be classified according to their impact on the environment and mankind. Investigation into wastes is necessary for identifying optimal technologies of their processing, storing and utilizing, as well as for compiling standards on waste generation and limits of their licenses, waste certificates
