【摘要】 以煤矸石酸溶物中和液为研究对象萃取分离稀散金属镓,主要考察萃取时间、萃取温度、萃取剂浓度、稀释剂种类对镓萃取率的影响。并通过响应曲面法对煤矸石中和液中镓的萃取工艺进行了研究。结果表明:实验值和预测值相近,可以用拟合模型对镓的萃取率进行分析预测,以确定最佳工艺条件。为工业煤矸石中和液中镓的提取提供依据。更多还原

【Abstract】 Using coal gangue pickle liquor as research object to extraction and explore gallium. Effect of extraction time,temperature,concentration and the kind of thinne on the extraction rates of galliumand were studied. Meanwhile,extraction of gallium from coal gangue pickle liquor by responce surface methodology were studied. The results show that: the result closes to the detected values, which indicating that the resulting model can reflect the true relationship between the parameters. This model can be used to analysising and forecasting for extraction rates of gallium. Determined the best molding process condition and providing the basis for industrial extraction of gallium from coal gangue pickle liquor production.更多还原
