process of extraction of iron ore from tailings

Rebeneficiation of iron ore tailings from the

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III)oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace.

iron extraction process equipment

Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.

dry process of iron ore extraction

This concentrated ore is mixed with limestone (CaCO 3) 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.
