在冶金部有色金属研究院广东分院和长沙有色冶金设计院的协助下,株洲冶炼厂从铅锌生产过程中综合回收In、Ge、Ga,73年9月至74年4月完成了小型试验,75年6月份结束了半工业扩大试验,确定了提取In、Ge、Ga的工艺流程。其原则流程是:置换渣氧化逆流酸浸→P_(204)萃铟→丹宁沉锗→中和沉镓和A_(101)萃镓。半工业性试验是在日产In 6～7公斤、GelOO～200克、Ga200～300克的
With the assistance of the Guangdong Branch of the Research Institute of Nonferrous Metallurgy and the Changsha Nonferrous Metallurgy Design Institute, Zhuzhou Smelter completed the recovery of In, Ge and Ga from the lead and zinc production process from September to April in 1974, In June 75, the semi-industrial expansion test was ended, and the process of extracting In, Ge and Ga was confirmed. The principle of the process is: replacement slag oxidation countercurrent acid leaching → P_ (204) extraction of indium → tannin germanium → neutralized Shen gallium and A 101 extract gallium. Semi-industrial test is Nissan In 6 ~ 7 kg, GelOO ~ 200 grams, Ga 200 ~ 300 grams
