Pig iron is crude iron as first obtained from a smelting furnace, in the form of oblong blocks.
The main impurities in pig are carbon (C) and Silicon (Si)
During the manufacture of Cast Iron, an intermediate product is Pig Iron. Further processing results in Cast Iron.

the team colors for the iron pigs are sliver, red, and blue
Pig iron is generally an intermediate product of the wrought iron and steel making process. Pig iron is virtually useless due to the very high impurity content. "Pure" is a strange quantification of the comparison between pig iron and wrought iron. Pig iron is pure pig iron and wrought iron is pure wrought iron if there is a "standard" for the respective materials. I'm guessing that the answer you want is that wrought iron is "more pure."
iron core , coke and limestone are needed to make pig iron

iron core , coke and limestone are needed to make pig iron
Pig iron is produced when heating * Iron ORE (not iron as the question says!) * Coke * limestone in a Blast Furnace.
During the manufacture of Cast Iron, an intermediate product is Pig Iron. Further processing results in Cast Iron.
pig iron is intermediate product of smelting of iron ore sponge iron is product of direct reduction of iron ore in solid state
No.
Where does Pig Iron come from? Pig iron is the intermediate product of smelting iron ore with coke, usually with limestone as a flux. Pig iron has a very high carbon content, typically 3.5-4.5%,[1] which makes it very brittle and not useful directly as a material except for limited applications.
http://encarta.msn.com/encyclopedia_761559225/iron_and_steel_manufacture.html Provides the answer. basic summary: 1. Pig Iron and Sponge Iron are the result of different production processes 2. Which results in different purities. Pig Iron has a lower purity than Sponge Iron.
yes it is!
