Process Of Separation Iron - Extraction of Iron | Metallurgy | Blast Furnace and Reactions

This fact is demonstrated by washing concentrates from the dry magnetic separation, when the iron content was easily raised from 52 to 58 per cent. This suggested using a combined process of dry magnetic separation …Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.

process of separating iron from ore - CN101480632A

Metal extraction is the process of extracting metal from its ore. The techniques for extracting metals from their ores and refining them are referred to as metallurgy. There is no single procedure that can extract all of the metals. The procedures to be employed differ depending on the metal.It's a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. 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.
