  • The Steel Manufacturing Process

     · Iron ore was first mined in Central Asia and Europe, and humans at this time used iron to make tools and weapons in a practice called ferrous metallurgy. Iron products evolved during this time, beginning with blacksmiths producing wrought iron goods. These tradespeople learned to heat up iron ore, and using a hammerandanvil process, the blacksmiths would remove impurities from the metal .

  • Iron ore mining and dressing

     · Iron ore processing. After the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation. Subsequently, the milled ores are lumped by sintering or ...
