| 摘 要： | 研究了拜耳法赤泥硫酸浸出镓的过程。硫酸浸出镓的溶液,用氢氧化钠反应生成沉淀,再用盐酸溶解沉淀提取镓的过程。采用正交试验考察浸出过程中温度、时间、液固比、浓度对镓浸出率的影响的主次顺序以及最佳条件。结果表明,该方法比单纯用盐酸浸出镓的浸出率高。镓的高浸出率是保证高的回收率的基础。

| Abstract: | The Sulfuric acid leaching process of gallium from Bayer red mud was studied.In this process the precipitating could be formed by reaction of the solution of sulfuric acid leaching with NaoH,and then the precipitation was dissolved in hydrochloric acid.The effects of leaching temperature, time,ratio of liquid to solid (L/S) and concentration of sulfuric acid on the leaching rate of gallium were investigated with orthogonal test, and the best conditions.The results show that Gallium is the basis of high leaching rates with high recovery. |
