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%.
