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.
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。
