On the basis of this analysis, the future production of iron and steel for the world is estimated. The historical analysis shows that the world iron ore production increased from 274 million tons (Mt) in 1950 to 1554 Mt in 2005, whereas the steel production increased from 207 to 1259 Mt. In addition, it is found that at the current level of production the world's identified iron ore reserves containing 230 billion tons of

The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process.
