what are iron mining techniques

The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:

strength of fired hematite pellets due to the absence of recrystallization and crystal growth of hematite until oC[14]. In addition to above, a huge amount of external energy is also required for induration of hematite ore pellets to obtain prerequisite pellet properties due to absence of exothermic heat of reaction.

In Orissa and Jharkhand the iron ore are associated with both the Banded Hematite Quartzite (BHQ) and Banded hematite Jasper. Bonai range of hills have 5563%Fe content. In Karnataka, there are two main types of iron deposits, the lateritoid hematitic iron ore concentrations with minor limonite and goethite and magnetite ore deposits.
