In this process, iron ore, coke (a form of carbon), and limestone are fed into the furnace, where intense heat and chemical reactions extract molten iron. Innovations in blast furnace technology, including hot blast systems, oxygen enrichment, and refractory materials, have significantly improved productivity and environmental performance.
This ore is either Hematite (Fe 2 O 3) or Magnetite (Fe 3 O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing. Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content.
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage.
