Mining exploration, extraction and beneficiation are now supported by highlevel technologies. The industry also promotes advancements in the areas of environmental, health and safety protection. The European mining industry is fundamental for the continent''s economic wellbeing.
Coal is a key raw material in steel production. Coal is primarily used as a solid fuel to produce electricity and heat through combustion. Coke, made by carburising coal ( heating in the absence of oxygen at high temperatures), is the primary reducing agent of iron ore.
The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks.
