Sintering Process Equipment Used in Iron and Steel

Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace.

Coal Mining and Processing | Energy Trends Insider

Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.

Coal | National Geographic Society

Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.

Coking Coal for steel production and alternatives - Front

Coal is needed as a reducing agent. “Reduction” is a chemical reaction that turns iron ore (Fe2O3) into pig iron (2Fe). Carbon monoxide (CO) is the crucial ingredient (Fe2O3 + 3CO → 2Fe + 3CO2) and is produced in blast furnaces by burning coal. This also produces carbon dioxide as a waste product.

From there, the coal is converted into coke and then used in the blast furnace-basic oxygen steelmaking process. Coal does three things in this process: it is burned to supply the huge amounts of heat required, it supplies gases to strip oxygen from the iron ore and roughly 1% of the coal ends up as carbon in the steel.
