中文摘要: 采用正交试验考察了盐酸浸出赤泥中镧元素的影响因素。结果表明，在下述最佳条件下镧浸出率可达96.67%：温度109 ℃（即沸点）、时间180 min、盐酸浓度8 mol/L、液固比8。
Abstract:The effects of process factors on leaching of lanthanum from red mud with hydrochloric acid were investigated by means of orthogonal experiment. The results show that the leaching rate of lanthanum is 96.67% under the optimum conditions including temperature of 109 ℃ (the boiling point of solution), time of 180 min, concentration of hydrochloric acid of 8 mol/L, and ratio of liquid to solid of 8.
