The extraction of iron from its ore The process of extraction of iron from iron oxide is as follows:, such as sand and mud present in the iron ore , are removed by washing in a current of water. By doing this, the percentage of the metal oxide in the ore
Extraction Of Iron From Its Oxides In a blast furnace oxide ores of iron, after concentration through calcination/roasting are mixed with limestone and coke are fed from its top. Hot air is blown from the bottom of the furnace and coke is burnt to give temperature up to about 2200K in the lower portion itself.
This concentrated ore is mixed with limestone and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag.
Smelting method used in the extraction of iron definition Smelting is the process in which ore is mixed with purifying or heat generating substance like limestone and coke, they are heated at high temperature in an enclosed furnace. The charge consists of roasted ore, coke and limestone in the approximate ratio of 12:5:3.
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace.
