The chemistry of steelmaking. Making iron.

What do we need to make iron? Making iron is the first step in the production of steel. Iron is usually made from iron ore, coal and limestone - although some plants around the world have developed alternative methods of iron manufacture.These newer methods require slightly different raw materials but iron ore, coal and limestone remain the starting point for most

Creating Iron HowStuffWorks

A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag. Liquid iron collects at the bottom of the blast furnace, underneath a layer of slag.

The History of Coal Iron Presses Our Everyday Life

28/09/2017  The charcoal iron is an ancestor to the modern electric iron. While today's irons use electricity to heat their metal bases and to generate steam, charcoal irons were heated by smoldering coals which were taken from a fire and placed inside a box on the top of the iron. The lid of the box had a handle which allowed people to hold the hot iron as they ran it over

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Iron Making Boundless World History

Use of coal in smelting started somewhat before the Industrial Revolution, based on innovations by Sir Clement Clerke and others from 1678, using coal reverberatory furnaces known as cupolas. With cupolas, impurities in the coal did not migrate into the metal. Abraham Darby made great strides using coke to fuel his blast furnaces at Coalbrookdale in 1709. However, coke pig iron was hardly used ...

10/09/2019  Iron ore is one of the basic among other raw materials used in the production of iron. It is described as any mineral substance that contains enough iron which makes its smelting a viable proposition, i.e an iron content if less than 20%. Ores vary considerably in form and composition from one source to another. Some ores are naturally being found as very hard rock, some as granular
