Iron and steel production involves extracting iron from its ore and converting it into steel. The process typically starts with mining iron ore, which is then smelted in a blast furnace. In this furnace, the ore is heated with coke and limestone, resulting in molten iron and slag. The molten iron can be further processed to create steel, which is an alloy of iron and carbon. This is done by removing impurities and adding specific amounts of carbon and other elements. The final product, steel, is widely used in construction, manufacturing, and various industries due to its strength and durability.
