Wrought iron is the purest form of iron. 

In extraction of iron from iron oxide in blast furnace, obtained iron contains 4% of carbon and impurities. This is known as Pig iron. This iron is melted using scrap iron and coke in hot air blast to get cast iron.  It is again heated in reverberatory lined with haematite to obtain purest form of iron known as wrought iron.
