A novel processing technique for efficient arsenic removal by collaborative roasting of low-grade tin middlings and lead smelting flue dust is proposed in this study. It is shown that FeAsS, the arsenic-bearing phase in tin middlings, decomposes into elemental As and FeS during roasting. These decomposition products can reduce arsenate phases in lead smelting flue dust into volatile As2O3, thereby realizing high-efficiency arsenic removal. With an addition of lead smelting flue dust at an amount of 30%, roasting at 700 ℃ for 90 min can lead to the arsenic removal rate reaching 94.73%.

提出了一种低品位锡中矿和铅冶炼烟尘协同焙烧高效脱砷的方法。结果表明,锡中矿含砷物相FeAsS在焙烧过程中分解生成单质As和FeS,两者可将铅冶炼烟尘中砷酸盐物相还原为易挥发的As2O3物相,继而实现砷的高效脱除。在焙烧温度700 ℃、铅冶炼烟尘添加量30%、焙烧时间90 min条件下,砷脱除率达94.73%。

提出了一种低品位锡中矿和铅冶炼烟尘协同焙烧高效脱砷的方法。结果表明,锡中矿含砷物相FeAsS在焙烧过程中分解生成单质As和FeS,两者可将铅冶炼烟尘中砷酸盐物相还原为易挥发的As2O3物相,继而实现砷的高效脱除。在焙烧温度700 ℃、铅冶炼烟尘添加量30%、焙烧时间90 min条件下,砷脱除率达94.73%。

A novel processing technique for efficient arsenic removal by collaborative roasting of low-grade tin middlings and lead smelting flue dust is proposed in this study. It is shown that FeAsS, the arsenic-bearing phase in tin middlings, decomposes into elemental As and FeS during roasting. These decomposition products can reduce arsenate phases in lead smelting flue dust into volatile As2O3, thereby realizing high-efficiency arsenic removal. With an addition of lead smelting flue dust at an amount of 30%, roasting at 700 ℃ for 90 min can lead to the arsenic removal rate reaching 94.73%.
