摘要
本文探索了[S_(612)—S_(610)]萃取剂对盐酸酸解磷矿的酸解液中磷酸的多级萃取。测定了等温萃取平衡线,求算了多级错流和多级逆流萃取的理论级数,提出了原则流程,为中试研究的工艺设计提供了依据。
The several grade extraction of the extractant(S_(612)-S_(610))extracting phosphoric from the solution,whichis made when chloric acid analysis phosphoric ore has been studied in thes paper. The extraction equibrium line has been detemined at the same temperature. The theory grades of several grades councurrent extraction and crosscurrent extraction have been calculated. All these provided a foundation for technical designing of further study in a factory.
