Explain the process of steel making. Solution: An iron-ore is a mineral substance that, when heated, yields metallic iron. Smelting of iron-ore is heating up the mineral with coal and limestone in an industrial oven to extract the iron. Molten iron is purified and converted into steel in a basic oxygen furnace by adding alloy metals.

Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.

Today, the manufacturing of steel is done by using one of these two methods: Blast furnace: The blast furnace process, also known as the basic oxygen process (BOP), combines raw iron ore with small amounts of steel scrap metal into a furnace. Then, pure oxygen is blown into the furnace, raising its temperature.
