摘　　要：采用贵州某地的一水硬铝石高硫铝土矿为原料,进行了氧化铝生产过程粗液脱硫试验研究,考察了反应温度、反应时间及脱硫剂用量对脱硫效果的影响程度,并通过单因素及正交设计确定了粗液脱硫的试验条件,试验结果表明:利用铝酸钡进行粗液脱硫仅在溶液中碳酸钠浓度较低的情况下适用。Using high sulfur-containing diaspore in somewhere ot Guizhou as raw material,resolution desulfurizing test in alumina production process was carried out. The effect of reacting temperature, re-acting time and dosage of desulfurizing additive on desulfurizing degree was investigated, and testing conditions for coarse solution desulfurizing were determined through signle factor and orthogonal design. The testing results shows that it is suitable for use that coarse solution desulfurizing was conducted by using barium aluminate only under lower concentration of sodium carbonate in solution.
