Iron ore

Today, iron ores are one of the most common minerals. Perhaps, only coal and construction materials are mined on a larger scale. More than 90 % iron ores are used in metal sector for producing pig iron and steel

Coal was the first kind of pit fuel used by man. It allowed bringing about the industrial revolution, which in turn contributed to the development of the coal industry by providing it with more modern technology

iron-carbon alloy containing more than 2.14 % carbon (maximum carbon solubility in austenite on the phase diagram). Carbon may be present in the form of cementite and graphite in pig iron. The following types of cast iron are identified depending on the graphite form and portion of cementite: white, grey, malleable and ductile iron

The type of minerals, natural mineral formation containing compounds of useful components (minerals, metals) in concentrations that make the extraction of these minerals economically feasible. Economic feasibility is determined by the condition of the ore
