Our anthracite is valued for its high carbon content, low impurities, and high calorific value. The main consumer is the metallurgical industry.
The ferrous metal industry is the main consumer of anthracite. Anthracite is used in the production of steel, cast iron, chromium, etc. The physical and chemical profile of anthracite allows for the production of high-quality metallurgical raw materials while reducing costs and environmental impact. The price of anthracite is lower than that of coke and comparable to the price of PCI coal.
The production process of anthracite is more environmentally friendly, compared to that of coke. In the chemical process industry, anthracite is used for the production of sugar and soda ash. In this area, low content of impurities and high heat transmission are also critical.
Raw anthracite is used as a natural substitution for coke. Anthracite fines are used in sintering, pelletizing, and PCI processes PCI consists anthracite and is used in blast furnace smelting of pig iron, thus reducing the consumption of expensive coke.

Usage in a ladle during the tapping from steel-making unit (convector, arc, and steelmaking furnaces). Carbon material of 0−10 fractions sits in a ladle during the tapping of the unit.
In ladle of ladle metallurgy facilities of LF type. Carburizing of steel is realized by coal injection (fraction 0−3mm) of steel liquid-alloy in inert gas current with the help of immersion lance. The set of bulk material (fraction 0−10 mm) onto the bared metal surface in the bottom tuyere operating zone for argon blow is possible.
Carbon material powder (fraction 0−3 mm) is injected into the liquid bath of arc steelmaking furnace simultaneously with the delivery of oxygen. Sponging is realized through CO bubble floating due to air oxidation of metal carbon. The usage of powder is usually 5−10 kg/t of steel. The arc is constantly closed by slag during the work with foamed slag that allows to exclude the negative influence of the arc on water cool element of the furnace and give ultimate output and thermal effectiveness. It increases the productivity of arc steelmaking furnace and reduces the energy consumption for steelmaking.
Calcined anthracite is frequently used as a recarburizer in ladle and blast furnaces in steel mills, and in producing carbon blocks and tamping paste. It is also used to replace calcined oil coke in specific applications in the production of ductile and grey irons.
