Creating Iron | HowStuffWorks
The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

Steel Production
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...

Chapter 5 Origin and Occurrence of Limestones
Summary. Limestones originate by three main processes: ( 1) precipitation of calcium carbonate in an initially stony condition, as in travertine and organic reefs; ( 2) lithification of calcium carbonate sediments, which includes various steps beginning with changes of grain mineralogy, and includes addition of concentric coatings to grains ...

A neural network model was used as a mapping function for ore grade prediction. The five principal components were used as input, and four grade attributes of limestone (CaO, Al2 O 3, Fe 2 O 3 and SiO 2) were used as output. The developed model was then used for day to day quality monitoring at 3 different face locations of the mine.
