Pig iron is regular iron. The "pig" part is from an older method of producing the molten iron. It was poured into a trough on the floor, and spread out into multiple side-troughs. After cooling, these side-troughs and main trough were broken up and shipped off.

Do you see it? the center trough (------) looks like a mother PIG, and the side-troughs (I) are the PIGLETS nursing on her side. See Wikipedia for explanation of why pig iron is a low quality form of 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."
What can pig iron be used for?
pig iron is a term modern blacksmith use for an iron alloy used in forging many basic tools
What are 2 good functions of iron?

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.

What is an iron production?
The production of iron or steel is a process containing two main stages, unless the desired product is cast iron. The first stage is to produce pig iron in a blast furnace. Alternatively, it may be directly reduced. The second is to make wrought iron or steel from pig iron by a further process.
Difference between pig iron and sponge iron?

Where did the phrase pig iron come from?
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.
