What Is The Method For Analysis Of Free Silica In Iron Ore

Carbon is reactive than iron, so it can push out or displace the iron from iron oxide. Here are the equations for the reaction iron oxide + carbon → iron + carbon dioxide 2Fe 2 O 3 + 3C → 4Fe + 3CO 2. In this reaction, the iron oxide is reduced to.At low SiO 2 content, the reduction rate increases with increasing CaO content. Turkdogan and Vinters 34 showed the influence of CaO and SiO 2 on the reducibility of iron ore pellets. They found that the effect of additional gangue depends on the sintering temperature and the porosity of the ores, and no general trends could be observed.
