    IntroductionIron Ore ExtractionIron Ore ProcessingSintering and PelletizingIron is one of the most important metals in mechanical engineering, as it is present in sufficient quantities on earth. The extraction of iron can therefore be very economical. However, pure iron is not suitable for use as a construction material. It is much too soft in its pure form and has too little strength to meet most mechanical requirements. For this reason, it is necessary to use alloying additives to give the iron its hardness and strength. It has been shown that carbon is an excellent alloying element. Within certain li
