R.Rácz等研究了用一种封闭式湿法冶金工艺从废Zn-C电池中回收锰和锌。首先将废旧电池分解并分类,然后进行机械和化学处理。所得的废电池活性物质用1mol/L的硫酸浸出,金属成分从固相转移到水相。酸浸液中含有6g/L Mn2+,65g/L Zn2+和190mg/L Fe2+。电解试验在阴离子交换膜反应器中进行,试验中采用恒电流法控制不同的电流密度,最大电流密度为50mA/cm2时电解产率最大。 R. Rácz et al. Studied the recovery of manganese and zinc from spent Zn-C batteries using a closed hydrometallurgical process. First, the used batteries are disassembled and classified, followed by mechanical and chemical treatment. The resulting waste battery active material was leached with 1 mol / L sulfuric acid and the metal component was transferred from the solid phase to the aqueous phase. Acid leachate contains 6g / L Mn2 +, 65g / L Zn2 + and 190mg / L Fe2 +. The electrolysis test was carried out in an anion exchange membrane reactor. The constant current method was used to control the different current densities. The maximum electrolysis yield was obtained when the maximum current density was 50mA / cm2.
