Abstract：
OBJECTIVE: Germanium, an important component of electronics, is considered by many global economies as a critical raw material. Therefore, investigating its potential new sources is crucial for prospective technology development. This paper presents the investigation results on the leaching of liquation-feeding furnace dross using sulfuric and oxalic acid solutions.
RESULTS: The dross contained mostly zinc (68.0% wt.) but also elevated germanium concentration (0.68% wt.). The influence of temperature, time, initial acid concentration, and liquid-to-solid phase ratio (L:S) was examined. It was found that germanium availability via leaching is limited-maximum leaching yields using aqueous solutions of sulfuric and oxalic acids were 60% (80 °C, 2 h, 15% wt. H2SO4, L:S 25:1) and 57% (80 °C, 3 h, 12.5% wt. H2C2O4, L:S 10:1), respectively.

摘要：
目标：锗，电子产品的重要组成部分，被许多全球经济体视为关键原材料。因此,调查其潜在的新来源对于未来的技术发展至关重要。本文介绍了使用硫酸和草酸溶液对加液炉渣进行浸出的研究结果。
结果：浮渣主要含有锌（68.0wt％。)，但也提高了锗浓度(0.68%wt。).温度的影响，时间,初始酸浓度,检查液固比(L:S)。发现通过浸出获得的锗是有限的-使用硫酸和草酸水溶液的最大浸出产率为60％（80°C，2h,15%wt。H2SO4，L:S25:1)和57%(80°C，3h,12.5%wt。H2C2O4,L:S10:1),分别。
