This web page summarizes information in PubChem about patent US-816142-A. This includes chemicals mentioned, as reported by PubChem contributors, as well as otherProcess of Steel-making from Iron Ore Huaruo ,In the past, pig iron was usually made at relatively low temperatures. The method is to place iron ore and charcoal in a furnace layer by layer and roast them slowly at a low temperature. Under these conditions, carbon monoxide produced by incomplete combustion reaction of charcoal can reduce the iron oxide in iron ore to iron elements, which can be formed into iron blocks after cooling, and pig iron can be obtained. This method of making iron

    2012-8-16 · FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase inHow is Iron Refined from Ore? (with pictures),Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore
