在铜的火法冶金中,如何减少磁性氧化铁对冶炼过程的危害,一直是人们极为重视的问题,尽管人们对此问题作过一些研究,但涉及动力学方面的工作不多,因此,深入研究Fe_3O_4-(xFeS·yCu_2S)-FeO-SiO_2体系的反应动力学就具有特别重要的实际意义。本文通过测定反应产生的SO_2来考察反应的进程,实验设备参见文献。 1.造渣熔剂对反应速度的影响冰铜对磁性氧化铁的还原是按下列反应进行的:
In the copper pyrometallurgy, how to reduce the harm of the magnetic iron oxide to the smelting process has always been a problem that people attach great importance to. Although people have done some research on this issue, they have not done much work on the kinetics. Therefore, Studying the reaction kinetics of Fe_3O_4- (xFeS · yCu_2S) -FeO-SiO_2 system has a particularly important practical significance. In this paper, by measuring the reaction of SO_2 to examine the progress of the reaction, the experimental equipment, see the literature. 1. Slag flux on the reaction rate of ice copper reduction of magnetic iron oxide is carried out according to the following reaction:
