i cant find in anywhere to answer this question.does iron ore can be reduced by mixing it coal and melting it.i mean can it be reduced in molten form?or more simply if you melt iron oxide and while its molten if you add coal powder can it be reduced?thanks
the fast answer is specific however the genuine answer is it relies upon. you're speaking approximately melting iron oxide so which iron oxide do you have? There are 3 and the melting factors are distinctive. then you could desire to look on the ambience, the soundness of iron oxides as f(temp) relies upon on the oxygen, CO, CO2, hydrogen partial pressures (and the presence of the different reducing gases). of direction in case you do decrease the oxide to iron metallic, it is going to react with the graphite crucible to form Fe3C, iron carbide, or, observing the ambience and temperature, possibly forged iron. seek for suggestion out of your friendly community extractive steel metallurgist.
Iron oxide (either iron II or iron III) melts at a very high temperature where the carbon of the coal would have already ignited if there were air around. Look up the Bessemer process where iron oxide is mixed with charcoal and air is forced through at a high temperature to cause the iron oxide to transform to carbon dioxide and molten iron.
