Abstract The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.

Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic properties.

The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the cokemaking process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...
