Explanation:
Impurities from iron ore can be removed through the following process-
During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of
fluxes such as limestone.
This slag floats on the molten iron and is collected at the base of the furnace at regular intervals.
The product obtained is known as pig iron which can be converted into wrought iron, steel and cast
