Slag - Wikipedia

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.

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...
