Raw materials used in making Iron and steel Studentlesson
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 of less than 20%. Ores vary considerably in form and composition from one source to another.2 Raw Materials. Impure iron is produced from reduction of iron ore by means of coke in a blast furnace. The product is a liquid iron, known as hot metal (3.5–4.5% C, 0.5–1.25% Si, 0.5–0.75% Mn, etc.) which is raw material for production of steel. Hot metal is refined by oxidation process to form steel.Raw Materials SpringerLink

(i) (a) Name two ores of iron. (b) Name three raw materials used
(b) Iron ore, lime stone, and coke are used in the extraction of iron. (c) Following are the reactions, which take place in the “Blast Furnace”, during the extraction of iron. (ii) Steel is an alloy of iron and carbon containing very small amounts of impurities, that are present in the cast iron. The carbon content varies from 0-5 to 1-5%.There is evidence that meteorites were used as a source of iron before 3000 bc, but extraction of the metal from ores dates from about 2000 bc. Production seems to have started in the copper-producing regions of Anatolia and Persia,where the use of iron compounds as fluxes to assist in melting may have accidentally caused metallic iron to Iron processing Definition, History, Steps, Uses, & Facts

Blast Furnace Extraction of Iron YouTube
This video uses animations to explain how iron is extracted from its ore in the blast furnace. It shows the reactions that occur at different levels of the f...Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others.Iron Extraction and Purification / Steel ChemKey

Draw the diagram of the blast furnace used in the extraction of iron
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.Bauxite is the main raw material used for the production of alumina (Al 2 O 3) through the well-known commercial Bayer process . This process has significant challenges such as limitation in using low-grade bauxites as they contain significant amounts of impurities such as Fe, Si, Ti.

Its Processing and Application in Iron and Steel Industry
Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight. There can be small particles of quartz (silica), feldspar (alumino-silicates), clay minerals, pyrite (iron sulphide), siderite (iron carbonate), andIron was one of the most basic requirements of the rapidly industrializing British economy, and the country certainly had plenty of raw materials. However, in 1700, the iron industry was not efficient and most iron was imported into Britain. By 1800, after technical developments, the iron industry was a net exporter.Iron in the Industrial Revolution ThoughtCo
