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
