In 1856, Henry Bessemer introduced, to London's Royal Academy of Science, a revolutionary process of converting iron into steel, which used the injection of a cold blast of air through molten iron in an eggshaped furnace—called a "converter"—that transformed iron into steel in a matter of minutes. Although accounts vary as to who actually "invented" the Bessemer process, we do ...

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.
