A kind of above-mentioned technique with copper sludge production electrolytic zinc can be further arranged to: the filters pressing is carried out using filter press
Filters pressing.
Copper sludge cleans before acid is molten in the present invention, in case Cl too high levels influence electrolytic process and electrolytic zinc
Quality.
The invention has the benefit that all waste liquids are recycled, therefore without fixation in technical process of the invention
Waste water output, the waste residue obtained in process of production, thin copper ashes, dross can not only be recycled and when without be recycled
When may be sold, waste residue zinc content about 46% can be sold to production zinc sulfate producer production zinc sulfate, thin copper ashes copper content is about
8% can be sold to copper works' copper metallurgy, dross zinc content about 89% can be sold to other producers production distilled zinc, not only environmental protection and meet
The strategy of sustainable development.
Below with reference to embodiment, invention is further described in detail.
