The extraction of metals and their isolation occurs over a few major steps: Concentration of Ore – Here the ore is separated from earthy impurities. Isolation of metal from concentrated Ore – Here the ore is converted to its oxide form and then reduced. The steps involved are either calcination or roasting and then heating with a reducing agent.

The extraction of iron from its ore is done in the following ways: 1. Concentration: During this process, the iron ore is crushed into pieces. These crushed pieces are concentrated by gravity separation method in which it is washed with water to remove sand, clay, and dirt. 2. Calcination: the concentrated ore is then calcined in a furnace.
