摘要：硫鐵礦制酸會產(chǎn)生燒渣，其砷含量與硫含量影響后續(xù)產(chǎn)品的質(zhì)量。本文通過試驗研究，確定適宜條件，對硫鐵礦精礦中的砷、硫進行脫除。試驗結(jié)果表明，選擇一段焙燒，焙燒溫度為900 ℃，焙燒時間為2 h時，脫砷脫硫效果很好。

Abstract： Slag will be generated during sulfuric acid production from pyrite， and its arsenic content and sulfur content can affect the quality of subsequent products. In this paper， the suitable conditions are determined to remove arsenic and sulfur from pyrite concentrate through experimental research. The experiment results show that the effect of arsenic removal and desulfurization is very good when the roasting temperature is 900 ℃ and the roasting time is 2 h.

Keywords： pyrite concentrate; arsenic removal; desulphurization
