Oct 10, 2017· Ironmaking Blast Furnace. A specialized type of coal, called hard coal, is used to make coke, a porous form of carbon. Coke is a reductant or a chemical that can reduce iron oxide to iron metal – especially when combined with heat and oxygen. Hard coal has highcarbon content and low ash, sulfur and phosphorus levels.

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. The iron content of these ores ranges from 70% down to 20% or less. Coke is a substance made by heating coal until it becomes almost pure carbon.

brown coal. Coal tar from bituminous coal is the liquid byproduct of the distillation of coal to make coke in the coke oven process. Coal tar can be further distilled into different organic products ( benzene, toluene, naphthalene), which normally would be reported as a feedstock to the petrochemical industry. 8.
