Iron ore is reduced to its metallic form through smelting which is called pig iron. It has a low melting point ( 12000C) as compared to steel ( 1400+). Depending upon the kind of reduction its Carbon content may vary between 4% to 3% with matching Silicon and Manganese content to make it harder or less harder, white, mottled or gray. Typically its hardness varies between 250 to 450 BHN( a measure of hardness), Tensile strength between 50 to 25 ks and % Elongation around 0 and 0.5. It comes in three qualities : White, Mottled and gray pig iron, name rendered as per their color and appearance. Pig iron is not used for working upon but it is the raw material for manufacturing various types of gray iron and steel.

Mechanical Properties of Ductile Iron. Ductile iron is characterized by having all of its graphite occur in microscopic spheroidsCast iron is formed by remelting pig iron, and is useful for a variety of engineering purposes.Properties and Uses of Iron. Iron is one of the three magnetic elements (the others are cobalt and nickel). Cast iron is very brittle (it cracks easily
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
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)
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.
