用高品位高硫铝土矿生产氧化铝时的除硫新方法研究
Research on the New Method of Desulphurizing In Producing Alumina with Exploitable Sulfur-Containing and High Grade Bauxite
【摘要】 本文研究了贵州高硫型高品位铝土矿溶出性能,考查了石灰添加量、溶出温度、苛性碱浓度和溶出时间对氧化铝溶出率的影响以及铝土矿的硫向溶液中的转化率(即硫的溶出率)的影响;还研究了用铝酸钡净化拜耳赤泥洗液的除硫条件和效果。
【Abstract】 The leaching function of high grade bauxite containing sulfur of Guizhou was studied.The effect of quantity of lime added,leaching-temperature,alkali-consistency and leaching-time on the yield of Al2O3 and the yield of sulfur were investigated.Meanwhile,the conditions and results of the desulphurizing were explored using the additive of Barium aluminate in the washable water of Baye pressure residues.
