is mixed with coke from super-heated metallurgical coal in a blast furnace. Air that has been heated to around 1,200 degrees Celsius is injected into the furnace, creating a flame temperature of 2,000 degrees. This converts the to molten pig and slag.

· for iron ore fines Like other processes, iron ore converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation.

Liberation can mostly be achieved at a very particle . Grinding and liberation leaves the in a finely ground state e.g. 100% minus 106 μm or generally 80% minus 44 μm that is not easily transported or readily processed in -steel making facilities.

· The particle size distribution of iron ore is a very important requirement to be characterized after its mineral processing. Materials containing a very fine particle size distribution are not adequate to be used directly in the reduction reactors, requiring to be agglomerated by different processes such as or pelletizing.

being unloaded at docks in Toledo, Ohio. ores are rocks and minerals from which metallic can be economically extracted. The ores are usually rich in oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The is usually found in the form of magnetite Fe 3 O 4, 72.4% Fe, hematite Fe 2 O 3, 69.9% Fe, goethite FeOOH, 62.9% Fe ...

is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement will need beneficiation of low grade /fines to get the major portion of increased demand. This paper deals in brief to of available methodologies for beneficiation in Indian context.

The arrival of blast furnaces, however, opened up an alternative manufacturing route this involved converting cast iron to wrought iron by a process known as Pieces of cast iron were placed on a finery hearth, on which charcoal was being burned with a plentiful supply of air, so that carbon in the iron was removed by oxidation, leaving semisolid malleable iron behind.
