降低铟萃取过程中有机相用量的研究

Research on reducing the amount of organic phase in the process of indium production

在精铟的生产过程中由于大部分物料含铟量较少,因此萃取成了提铟的一种不可缺少的除杂富集方法,而有机相则是萃取过程中必要条件。所以在保证萃取率的前提下降低有机相用量有着实际的生产意义。本文主要从料液酸度、料液净化程度、相比、温度、有机相再生方面结合生产情况确定了萃取最佳工艺条件,有效的降低了生产成本。

In the process of indium production due to the majority of the material with less indium content, extraction has become an indispensable part of the extraction of indium enrichment method, and the organic phase is the necessary conditions for the extraction process. So it is of practical significance to reduce the amount of organic phase under the premise of ensuring the extraction rate. In this paper, the optimum conditions of extraction were determined by the combination of the acidity of the material, the degree of purification, the temperature and the organic phase, and the production cost was reduced.
