What is iron ore Iron ore is a mineral aggregate that contains iron element or iron compound and can be used economically. It can be used for refining elemental pig iron, steelmaking and many other purposes. About 98% of iron ore is used to produce iron, it is one of the important sources used to refine steel. In steel mills, natural ore (iron ore) undergoes …
The symbol equations for the different stages of the extraction of iron from hematite are: Zone 1: The burning of carbon (coke) to provide heat and produce carbon dioxide:; C (s) + O 2 (g) → CO 2 (g). Zone 2: The reduction of carbon dioxide to carbon monoxide:; CO 2 (g) + C (s) → 2CO (g). Zone 3: The reduction of iron(III) oxide by carbon monoxide:
Iron is the main impurity ore for the purification and whitening of kaolin. Its occurrence state is diverse, often in the form of hematite, pyrite, siderite, limonite, anatase, ilmenite and other mineral forms, and sometimes it …

Purification of the metal ... • Electro Refining: It is the process of using electrolysis to increase the purity of a metal extracted from its ore (compound or mixture of compounds from which a metal can be extracted commercially ...
Iron ore isn't pure iron oxide – it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide.
