Extraction of Iron from its ores, Iron dressing, Reduction ...

Purification & concentration process is the process of using surface tension properly, magnetic or electrical separation to remove the unwanted impurities which are chemically combined or mixed with ore to increase the percentage of iron in the ore. Ore-dressing process is also carried out to improve the chemical properties of ores by roasting, It means heating the substance strongly in the air for drying the ore, expelling humidity, converting the iron ore into oxide, increasing the ratio ...

The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: 1) Concentration. The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated by gravity separation process in which it is washed with water to remove clay, sand, etc. 2) Calcination

The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source - as you will see below.
