摘要
硫铁矿制酸过程中,电除尘器收集的硫铁矿烧渣的铁含量较低,混入到烧渣后,致使整个烧渣的含铁品位降低。本试验研究通过水洗、化学方法除硫除钙及其它可溶解的盐类杂质,提高烧渣的品质,从而提高烧渣的价值。
In the process of pyrite sulphuric acid production, the iron content of pyrite cinder collected by electrostatic precipitator is relatively low. When mixed into the cinder, the iron content of the whole cinder decreases. In this experiment, the quality of cinder is improved by water washing, chemical desulfurization,calcium removal and other soluble salt impurities, so as to improve the value of cinder.
