The coke is a source of carbon monoxide which will reduce the iron oxide in the ore to iron and the carbon monoxide oxidizes to carbon dioxide. The limestone acts as a flux to remove other impurities and help the iron physically separate from the rest of the burden. It comes out carrying a lot of the other impurities as slag.

Calcination of Limestone. High calcium – The carbonate content is composed mainly of calcium carbonate with a magnesium carbonate content not more than 5 % (usually less). Magnesium – This contains magnesium carbonate to about 5 – 20%. Dolomitic This is also known as dolomite and contains over 20 % of MgCO3.

The calcination process normally takes place at temperatures below the melting point of the product materials. One of the most common applications is as a step in the production of Portland cement, in which calcium carbonate (limestone) is calcined at around 850°C to produce calcium oxide (quicklime) and carbon dioxide.
