摘　　要：介绍了硫在铝土矿中存在的形态、硫及其化合物对生产工艺、产品氧化铝质量的影响。对浮选法、碱性铝酸盐溶液浮选法,电位调控浮选法、碱石灰烧结法以及添加脱硫剂的氧化铝湿法除硫等几种脱硫方法的主要优缺点作了简要评述,详述了氢氧化钡、铝酸钡、氧化钙脱硫剂湿法脱硫的原理及其特点。The form of sulfur and effect of sulfide on technics and product alumina were introduced in the article. The main advantages and disadvantages of several methods of desulfuration were discussed including floatation,floatation in the basic aluminate, potential floatation, soda-lima sintering process and the hydro-methods depended on desulfurizers to desulfurize. The principle and characteristics of several desulfurizers including barium hydroxide ,ammonium barium, calcium oxide were expanded.
