用“H”试剂从氧化锌酸浸液中回收锗的试验研究

Study of Ge Recovery with H Extractant from H_2SO_4-leached Solution of Zinc Oxide

用“H”＋煤油＋添加剂作萃取剂，对锗的回收工艺进行了研究。结果表明：对于含锗为0．02～0．03g／L的氧化锌酸浸上清液，用”H”＋煤油＋异辛酸（或TBP）萃取回收锗，不仅试剂消耗小，而且产品（锗富集物）含锗可达22％以上。

Study is made on Ge recovery from H2SO4-leached supernatant (0. 02 ～0' 03 g/lGe), using 'H' kerosene and butyl octano TBP as extractant. Resljlts show that the said processfeatures lower reagent consumption and over 22% Ge content in concentrate.
