“…This material can be used for melting in OTF only in the pelletized form [19][20][21]; our further research is aimed at selecting the binder and determining the optimal pelletizing parameters. Recycling of carbon-containing waste generated during the production of PA for the electrolytic production of aluminium will also contribute to improving the environmental situation near sites of metallurgical production [22,23].…”

The production of metallurgical silicon is carried out in ore-thermal furnaces by reducing silica-containing raw materials with a carbon reducing agent, the most reactive of which is expensive and scarce charcoal. For the purpose of possible partial replacement of charcoal in the charge for silicon smelting, we conducted studies on the properties of carbon-containing technogenic raw materials formed in the process of obtaining pre-fired anodes for aluminium production. The object of research was 2 samples of dust from the mixing and pressing compartment: from the aspiration units and from the cleaning of the shop. The characteristics of these samples (carbon content, granulometric composition, humidity) were determined. To activate these carbon materials, ultrahigh-frequency processing was used at various capacities and durations. When studying the reactivity of the dust samples by the method of heteroelement analysis using the Vario MICRO cube analyzer, it was found that a sample of dust from aspiration plants treated with ultrahigh-frequency radiation at a power of 80 W and a duration of 40 min more actively interacts with oxygen to form CO2, which makes it possible to recommend this carbon-containing technogenic material as a reducing agent for smelting metallurgical silicon.

In the studies of the state of land areas performed using the advanced methods, in images from space, the industrial region around the city of Norilsk can be seen as a blurred spot that occupies an area of more than 900 km2. Among diverse pollutants forming the picture, sulfur and nitrogen compounds, nitrates, sulfates, phenols, industrial dust, and heavy metals have a particular impact. The release of sour gases results in acid rains, which are among the major pollutants forming the whole picture. These substances affect humans, all objects of the environment, and sources of anthropogenic activities including engineering installations of power plant enterprises. The direct impact on the state of metal towers decreases significantly their lifetimes and increases the risk of emergencies. In this paper, the research data on the state of power line towers of different types are provided and the effect of acid precipitation on structures is shown.
