硫化物的氧化过程是有色冶金中一项极为重要的过程。近年来在硫化物的氧化方面有许多研究工作报道,但多半偏重于对这一过程的化学机理的研究。而硫化物氧化是一多相放热反应,正如其他多相反应一样,我们不仅要知道硫化物氧化的化学反应,而且要知道它的反应速度。后者对于生产实践具有更大的实际意义。 Sulfide oxidation is a very important process in non-ferrous metallurgy. In recent years there have been many reports on the oxidation of sulfides, but most of them focused on the chemical mechanism of this process. Sulfide oxidation is a heterogeneous exothermic reaction. Just as with other heterogeneous reactions, we should not only know the chemical reaction of sulfide oxidation, but also know its reaction rate. The latter has more practical significance for production practice.
