Abstract:

In this study, a batch recycle process for recovering valuable metals contained in mixed batteries waste (manganese-alkaline batteries; nickel-cadmium batteries; and nickel-metal hydrate batteries) was established. This recycling process consists of stable heat treatment, physical pretreatment and hydrometallurgy processes. Stable heat treatment process prevented fire and explosion by batteries waste. After pulverizing the heated batteries waste, each metal was concentrated and separated into magnetic and nonmagnetic materials by magnetic separation process. Separated nonmagnetic materials were recovered with high purity ZnMnSO4, Zn metal and MnSO4 through hydrometallurgy process such as leaching, solvent extraction, vacuum distillation and electrolytic extraction.
