World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Iron processing Iron processing Iron making The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
