Fe_3O_4是磁铁矿石中主要含铁成分。我国很多大的铁矿是磁铁矿,例如鞍山铁矿、攀枝花铁矿和迁安铁矿。在有些自然铁矿石中含有一定量的含钾和钠的脉石。在选矿和烧结后仍进入最后的矿石球团中,对于矿石在高炉中的行为有很大的影响。所以研究钾、钠化合物对Fe_3O_4的氧化和还原行为的作用是很必要的。
Fe_3O_4 is the main iron ore magnetite composition. Many of our country’s large iron mines are magnetite, such as Anshan Iron Mine, Panzhihua Iron Mine and Qian’an Iron Mine. In some natural iron ore contains a certain amount of potassium and sodium gangue. Into the final ore pellets after beneficiation and sintering have a significant impact on the behavior of the ore in the blast furnace. Therefore, it is necessary to study the effect of potassium and sodium compounds on the oxidation and reduction behavior of Fe_3O_4.
