中文摘要: 在950~1 100 ℃,通过模拟硫酸渣的高温氯化还原焙烧过程,考察了铅的氧化物和硅酸盐的还原脱除行为。结果表明,还原过程中,铅的氧化物和硅酸盐均能被有效脱除;铅的氧化物比其硅酸盐更容易被还原脱除;还原气氛对球团中铅的还原脱除影响非常显著,强还原气氛对硫酸渣中铅的脱除有利。
Abstract:Removal behaviour of lead oxide and lead silicate at the temperature range of 950~1 100 ℃ was investigated to simulate high temperature chlorination-reduction roasting process of pyrite cinder. The results show that lead oxide and lead silicate can be removed effectively during reduction. It is easier to remove lead oxide than to remove lead silicate. In addition, reducing atmosphere is important to remove lead during reduction, in that strong reducing atmosphere is in favor of lead removal in pyrite cinder.
