Pig iron was originally used in neo-bronze age in the production of tools and weapons. It involved the smelting of iron ore with the hypolectatic acid found in pig hooves. The mixture increased the malleability of the iron but was to some degree a poisoned chalice, as it increased the rate of oxidisation of the metal and ultimately weakened it, rendering it worthless. The phrase "to do something for pig iron" emerged at the beginning of the industrial revolution in Britain and means that one does something despite knowing that the end result of the action is destined to be pointless.

Where does pig iron comes from?
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.
Why is pig iron called pig iron?
Definition of Pig Iron: The term was derived from the method of casting the bars of iron in depressions or moulds formed in the sand floor adjacent to a furnace. These were connected to a runner (known as a sow) and when filled with metal the runner and the numerous smaller moulds were supposed to resemble a litter of suckling pigs, hence the term pig iron.pig iron is called pig iron because due to it shape and molds. When the iron come out from its mold due to it contain % of carbon and it look black pigs, when it come out of it mold it look like pigs standing in a group so it is called pig iron. answered by vsp the king
Where did the phrase sweat like a pig come from?
The phrase "sweating like a pig" actually has nothing to do with the animal that you might find on a farm. Instead, it refers to iron "sows" and "piglets" made when smelting pig iron. In traditional iron smelting, liquid iron is poured into a mold shaped like one long line with many smaller lines branching off of it at right angles. This looks similar to piglets feeding from their mother, so these pieces became known as pigs. After the pigs are poured into the sand, they cool, causing the surrounding air to reach its dew point and turn into moisture on the pigs, like they are sweating. When the pig is sweating, it's cool enough to be moved.
Is pig iron magnetic?
Yes, pig iron is magnetic due to its high iron content. The iron atoms in pig iron are arranged in a way that makes it magnetic, allowing it to be attracted to magnets.

How do you make pig iron?

Which is purer wrought or pig iron?
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."
