WhatsAppGet PriceGet A QuoteIron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
WhatsAppGet PriceGet A QuoteThis 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.

WhatsAppGet PriceGet A QuoteGENERAL OVERVIEW. Iron is extracted through a method called reduction. Raw materials used in the extraction of iron are: Oxygen has to be removed from iron (III) oxide chemically to obtain iron. Iron (III) oxide is reduced when oxygen is removed from it. A blast furnace is used for this process [Figure 4].
