Roasting

The temperature to which the ore is heated depends on the specific ore and on the purpose of roasting Iron ore can be subjected to a magnetizing roast, which is usually reductive and converts iron oxides into the magnetic form for subsequent enrichment; this process is carried out in reverberatory kilns, shaft furnaces, or fluidized bed furnac.

smelting

In the smelting process a metal that is combined with oxygen—for example, iron oxide—is heated to a high temperature, and the oxide is caused to combine with the carbon in the fuel, escaping as carbon monoxide or carbon dioxide Other impurities, collectively called gangue, are removed by adding a flux with which they combine to form a slag.
