Therefore higher iron ore feed content to blast furnace is always preferred. Indian hematite, though rich in iron content has a higher content of alumina and lower silica content. Alumina to silica ratio is as high as 1.5–3%. Adverse alumina to silica ratio is detrimental for the blast furnace. This should be less than 1.5 and preferably below 1.

The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and

2023.3.25 Beneficiated ores provide increased value because their lower gangue content reduces the flux (lime) and fuel (coke) required for melting and separation of the gangue (as molten ‘slag’) in the blast furnace [1]. Iron ore beneficiation encompasses a wide range of process steps.

History of use of iron ore pellet in blast furnace The history of pellets began in 1912 when A.G. Andersson, a Swede, invented a pelletizing method. The commercial use of pellets, however, began in the USA after World War 2. Various studies were conducted with the aim of developing the vast reserves of taconite in the area around the Great Lakes.
