sponge iron process vs cement process

What is the application of iron mill scale? Can I extract.Iron mill scale can be recyled in steel plants as a mix component in production of iron ore sinter. It can be used in along with other iron bearing materials in for production of sponge iron. Mill scale after proper cleaning and treatment can be used for production of iron powders for use in powder metallugy applications.sponge iron plants manufacturers and sponge iron equipmentsThe process was widely accepted by almost all developing countries where generation of scrap was less in comparison to requirements. Steel produced by recycling process found much cheaper than the steel produced by blast Furnace process. The scrap vanished gradually causing threat to the Arc furnace where.
