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. What happens in the Blast ...
Dolomite is mainly used as blast furnace flux, as a source of magnesium salts and in fertilizer and glass industries. Iron and Steel industry is the chief consumer of dolomite [90 per cent] followed by fertilizer, ferro-alloys and glass. Dolomite is widely distributed in the all parts of the country.
Pellet plants can produce two varieties of pellets: blast furnace pellets and direct reduction pellets (DR pellets). Blast furnace pellets are used in the coke-based blast furnace process, which is the most common method of producing hot metal (molten iron for steelmaking). Blast furnace pellets are delivered mainly to steel mills.

Refining and extraction: The obtained ore containing iron oxides are first reduced in the blast furnace or electric furnace along with carbon to yield the ferromanganese and silico furnace.This is the main product to give rigidity and to reduce corrosiveness of the steel.
A blast furnace charge consists of coke, ore or sinter, and limestone. These materials must be in lumps of a certain size (40-60 mm). Larger lumps prolong the process of reduction and fluxing. Smaller lumps block the flue-gas passages and prevent a uniform descent of melting materials in the furnace. 2. IRON ORES: Ore is a metal bearing mineral.
Extraction and refining. Pure manganese is produced by hydrometallurgical and electrolytic processes, while ferromanganese and silicomanganese are produced by the smelting of ores in a blast furnace or, more commonly, in an electric furnace.

MnO 2 + 2C → Mn + 2CO. Ca 3 (OH) 2 → CaO + P 2 O 5. 2P 2 O 5 + 10C → P 4 + 10CO. Collection of Cast iron: Metal is cast into ingots or in the ladle for further refining like steel making. Wrought Iron: Minimum % of carbon is 0.1 – 0.1% and other impurities like S, P, Mn, Si less than 0.3% Manufacturing Process: Cast iron is taken in pudding furnace and melted by hot blast of air.
Ferro-manganese (Fe-Mn) is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron (Fe) and manganese (Mn) with a minimum Mn content of 65 %, and maximum Mn content of 95 %. It is produced by heating a mixture of the oxides of Mn (MnO2) and iron (Fe2O3) with carbon (C) normally as coke or coal.
