From there, the ore is transported to a separate facility for smelting, which is: The process of melting the ore concentrate in a furnace to separate the metal. Then, the ore is poured into molds to make bars of bullion. Closure/Reclamation Once the ore has been processed and shipped away for sale, the final step of the mining process begins.

Operation. In the standard SL/RN process, iron ore, coal, and dolomite or limestone as desulfurizing agent are charged into a rotary kiln and heated up by a countercurrent gas flow. Heat is generated by the controlled combustion of volatiles from the coal and surplus CO from the charge. The reduction of iron oxides in the solid state is ...

Blast furnaces are used continuously and are only shut down when their lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
