of zinc since 1980s and its production accounts for more than 80% of the total quantity [1]. However, for zinc electrowinning process, there is of a shortage of high electricity consumption and about 75% of the total electricity consumption is used for zinc electrowinning [2]. Therefore, the key of energy efficiency for zinc hydrometallurgy technology lies in reducing the electricity consumption......
