CHEMISTRY: The extraction of Iron and its impact on the. 04/09/2012
Raw materials vary widely in cost What purity is needed, and are the purification methods expensive? Some metals are not useful unless very pure, others are useful impure How much energy does the process use? High temperatures and electrolysis use a lot of energy How efficiently, and in what quantities, can the metal be made? Continuous processes are more efficient than batch processes
Raw Materials Used In Extraction Of Iron. Solvent extraction of ironiii iii from raw materials or industrial wastes is very important. efficient recovery depends on the effective means of separation of feiii, which promote people to develop new more effective separation technologies. this is also in line with the demand of the modern industrials.
i a Name two ores of iron. b Name three raw materials used in the extraction of iron. c Write equations that occur in the Blast Furnace.
There are several different types of iron ore, but in the modern world just the two taconite and hematite.
19/11/2018· For the production of steel, there is a need for iron raw material in the form of iron ore or scrap metal, together with alloying elements so that the material acquires the desired for properties. In the production of ore based steel, coal is also needed as a reducing agent and limestone as a slag former.
Iron Ore, Coke and Limestone are mixed together and fed into the top of the blast furnace. Hot air is blasted into the bottom of the blast furnace. Coke is used as the starting material. It is an impure carbon and it burns in the hot air blast to form carbon dioxide.
Raw materials are the starting materials for an industrial process, obtained from nature. raw materials used in the extraction of iron? Haematite : Carbon dioxide : Limestone : Coke : Iron : Inside the blast furnace. The coke is added to the haematite to provide a . reducing agent . A reducing agent is an elementpound that removes oxygen frompound or provides electrons in a
Step 1: extraction of raw materials The raw materials needed to produce cement calcium carbonate, silica, alumina and iron ore are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by
16/09/2013· According to this broad definition, bloomeries for iron, blowing houses for tin, and smelt mills for lead would be classified as blast furnaces. However, the term has usually been limited to those used for smelting iron ore to produce pig iron, an intermediate material used in the productionmercial iron and steel.
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 includeite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70 down to 20 or less.
