This paper reviews secondary Zn resources treatment developments and state-of-the art recycling technologies in the last decades. Sustainable and environment friendly novel hydrometallurgical technologies for secondary zinc extraction may overcome tougher legislations and meet cost competitiveness.
For WEEE, the routes are based on common hydrometallurgical technologies used to extract metals from ores. The strength of these technologies when compared to pyrometallurgy lies in the possibility to process low-grade and chemically complex streams to obtain final products of very high purity.
2019/06/21· ZnO, a resultant product of hydrometallurgical recycling of zinc-containing dust produced by the remelting of steel waste in an EAF, was used for this research. From the resulting product containing 79.04% Zn, five varistor
A total of 26,928 and 26,940 tonnes of alkaline, zinc–carbon and zinc-air batteries were recycled in 2006 and 2007, respectively, by European Battery Recycling Association (EBRA) members (). More than 15 billion of acidic or alkaline Zn–Mn batteries have been produced annually after 2002 in China ( Nan et al., 2006 ).
