Smelting Reduction Processes
In SR processes, iron ore and coal are added directly to a metal-slag phase where the ore is reduced. The SR process combines the gasification of coal with the smelting reduction of iron ore. Energy consumption of smelting reduction is lower than that of blast furnace, as coking step is avoided and the need for ore preparation is reduced.

What's the Process of Iron Smelting?
There are two kinds of slag formation in blast furnace. When smelting with ordinary acid ore, the flux is loaded into the blast furnace in the form of limestone, and the Cao in the flux can not be in close contact with the acid oxides in the ore. therefore, the slag initially formed is mainly fe2sio4 formed by SiO2, Al2O3 and a part of reduced FeO.
