Process of Steel Manufacturing | JSW MI
Iron-making. This is the first step in the manufacturing of pure steel. In this step, the raw materials like iron ore, coal and lime are melted in a blast furnace. This results in the formation of molten iron, also known as hot metal, which still contains 4-4.5% of carbon and other impurities, which makes it brittle.

Draw the diagram of the blast furnace used in the extraction …
Hint: We have to draw the diagram of the blast furnace used in the extraction of iron. It is used for the common ores like iron oxides to extract the iron with the help of reduction with carbon. The apparatus consists of many parts like hot air blast, tap hole etc. Design the blast furnace. First, let us know about the use of blast furnaces.

Iron- and Steel-Making Process | SpringerLink
Iron is extracted in the form of metallic iron (Fe) by reducing the oxide ores with a reducing agent. The principal agents commonly employed to serve this reduction process are the naturally occurring forms of carbon such as coke, charcoal and coal. In order to extract the iron, Fe (55–60%)-rich ore is usually used.

Extraction of Aluminium (Aluminium Ore)
Hall-Heroult Process. The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with a lining of carbon and graphite rods is used.

Extraction of Zinc: Process, Ores, Diagram
The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.
