Production of Pig Iron from Magnetite Ore–Coal Composite

Magnetite ore–coal composite pellets with about 10, 15 and 20mm diameter were rapidly smelted to produce pig iron by microwave heating in N 2 gas. A microwave generator with 5kW maximum power at 2.45GHz was employed. Carbon content in pig iron was about 2mass% near the liquidus line in the Fe–C system. Slag was easily separated from pig iron.

Pig iron Wikipedia

Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.

Metallurgical coal is used to make coke for the iron and steel industry, foundries, and other industries. Coke is used to smelt iron ore in the blast furnace in the steel making process, acting both as a source of heat and as a chemical reducing agent, to produce pig iron, or hot metal. Globally around 70% of steel produced relies on coal.
