摘　　要：研究了一氧化碳还原焙烧褐锰矿,通过回转管式炉模拟工业回转窑试验确定了还原焙烧最佳工艺参数。试验结果表明,在物料粒度-100~120目,焙烧温度850°C,焙烧时间30 min,CO流量为90 L/h的条件下,褐锰矿的最高还原浸出率达到97.33%。The reduction and roasting of braunite by carbon monoxide is studied, and the optimal process parameters of reduction and roasting is confirmed through the test that the rotary tube converter to simulate industrial rotary kiln. The test results show, when the material particle size is - 100 - 120 mesh, the roasting temperature is 850, the roasting time is 30min, CO flow is 90L/h, the highest leaching efficiency of braunite can reach to 97.33%.
