研究了锰矿石还原焙烧脱砷，通过对比试验，确定了脱砷工艺及最佳工艺参数。试验结果表明，通CO气体并加石油焦还原焙烧，脱砷效果最好；在物料粒度0．5～0．75 mm、焙烧温度1100℃、焙烧时间2 h、CO流量1．5 L/min、石油焦加入量20％条件下，砷脱除率为97．13％。
研究瞭錳礦石還原焙燒脫砷，通過對比試驗，確定瞭脫砷工藝及最佳工藝參數。試驗結果錶明，通CO氣體併加石油焦還原焙燒，脫砷效果最好；在物料粒度0．5～0．75 mm、焙燒溫度1100℃、焙燒時間2 h、CO流量1．5 L/min、石油焦加入量20％條件下，砷脫除率為97．13％。

The removal of arsenic from manganese ore by reduction roasting has been researched . Suitable process for removal of arsenic from manganese ore was selected through contrast tests ,and optimum conditions were determined .The removal rate of arsenic could reach 97 .13% when the reduction roasting was taken in monoxide atmosphere under the conditions of material size of 0 .5~0 .75 mm ,roasting temperature of 1 100 ℃ ,roasting time of 2 h ,CO flow of 1 .5 L/min ,petroleum coke amount 20 percent .
