The process of refining iron from its ore involves several phases, the most important being the process of putting the iron ore in a form that can easily be used in industries. Here's an overview of the process: Concentration of Ore. Mineral iron is extracted and then it goes through a further process in which it is pulped or crushed.

Mineral deposit

There are two major types of deposit. The first, and by far the most important, is banded iron formations (BIFs), so called because they are finely layered alternations of cherty silica and an iron mineral, generally hematite, magnetite, or siderite. BIFs can be divided into two kinds.

18 Facts About Iron Ore

Iron Ore

Pig iron is an intermediate step in the production of steel and is produced by smelting iron ore (commonly in lump, pellet or sinter form) in blast furnaces. The removal, by oxidation, of impurities in pig iron such as silicon, phosphorus and sulfur and the reduction in the carbon content, results in the production of steel.

Iron

About 98% of world iron ore production is used to make iron in the form of steel. Iron in cast form has many specific uses (e.g. pipes, fittings, engine blocks) but pure iron is quite soft. Adding a small amount of carbon (usually less than 1%) makes iron into steel which is significantly harder and extremely versatile.
