【摘要】 利用自制的铝酸钡对高硫高铝型铝土矿在氧化铝生产中的赤泥洗液进行净化脱硫试验,以降低铝酸钠溶液中硫的含量。从脱硫温度、时间和铝酸钡的添加量对脱硫率的影响等方面进行研究。利用铝酸钡净化铝酸钠溶液的最佳条件为:65℃、20min、铝酸钡添加量100%,其脱硫率可达到95%。更多还原

【Abstract】 The desulfurizing from red mud wash liquor with barium aluminate is tested.The effects of operation parameters such as temperature,time,additive content of barium aluminate were investigated.The efficiency of sulphur removal could reach 95% under the optimal conditions: 65℃,20 min and 100% additive content of barium aluminate.更多还原
