iron ore processing methods

The Making of Iron Steel

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as gangue. The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
