Blister Copper Electrolytic Refining Process Equipment

With the accelerated renewal of electronic products, a large amount of electronic waste is recycled, which contains a large amount of metallic copper resources. However, due to the low purity of crude copper, containing impurities such as iron, lead, silver, gold, etc., to obtain high purity copper with a purity of 99.99% or more, the electrolytic refining process has become a key step, which is widely used in the smelting system of recycled copper.

Electrolytic refining process and equipment introduction

Blister Copper Electrolytic Refining Process Equipment

Electrolytic refining first needs to cast the crude copper into anode plate, ready to be put into the electrolytic tank. Under energized conditions, the crude copper anode is gradually dissolved in the electrolyzer, pure copper is deposited on the cathode plate in the metallic state to form electrolytic copper, and impurities are deposited to form anode mud. The electrolyte flows continuously in a special circulation system to keep its composition stable and extend its service life through a filtrate regeneration system. The anode sludge is rich in precious metals and can be used to further extract valuable metals such as gold, silver, and palladium.

Equipment Configuration and Optimization Suggestions

According to different output requirements, the electrolytic refining line can choose a manual or automatic anode plate changing system, small or large electrolyzer, electrolyte cooling, and circulating system, anode sludge collecting device, and so on. Investment costs and operation and maintenance costs need to be considered in a balanced manner. Small-scale production focuses on ease of operation and energy consumption, while large-scale refining focuses on automation and capacity efficiency. Reasonable configuration of equipment can significantly improve the stability and economic efficiency of the whole system.

The role and value of key technical equipment

In the electrolytic refining of crude copper, the electrolyzer, power control system, electrolyte management system, and anode sludge treatment equipment form the core of the process. Together, they ensure the stability of the electrolysis process, the high-purity extraction efficiency of copper, and the effective recovery of precious metals. As an important link in the field of recycled metal recovery, electrolytic refining equipment helps to achieve the dual goals of maximizing the use of resources and environmentally friendly production.
