Copper Electrolysis (Electro-refining)

Metalcess Intelligent provides Copper Electrolysis (Electro-refining) Plant to produce cathode Copper (Cu≥99.96%) from Anode Copper (Cu≥98%). If the Copper anode has precious metals content, the precious metals will go to anode slime and can be further recovered. The copper electrolysis system provided by Metalcess is the IAS method, which uses permanent stainless steel cathode plates instead of cathodes made from starting sheets. The cathode Copper is stripped from the permanent cathodes. A mini-capacity of 4ton/day Copper stripping system is self-developed by Metalcess to meet small and medium capacity project requirement.

Raw Material; Output Product

Input: Copper Anode (Cu≥98%)

Output: Cathode Copper (Cu≥99.96%)

Detailed Description

The Copper anodes after fire-refining generally contain over 98.5% Copper. To further remove impurities and comprehensively recover other valuable metals, it needs be purified in electro-refining system.

The Copper electrolysis system provided by Metalcess is the IAS method, which uses permanent stainless steel cathode plates instead of cathode made from starting sheets. With this, the cathode Copper is stripped from the permanent cathodes. If the Copper anode has precious metals content, the PMG will go to anode slime and can be further recovered. The permanent stainless steel cathode plate service lifetime can be 10 years.

The minimun capacity of Copper stripping system can start from 1ton/day to meet various clients requirement.

Technical and economic indicators:

Copper recovery: 99.6 - 99.8%

Direct current energy consumption: 230 - 280 kW·h/t of copper.

ISA Copper Electrolysis System Advantages

ISA Copper Electrolysis System Advantages

(1) The permanent S.S. cathode plates can be reused, eliminating the need for an electrolytic cell system for producing starter sheets and also the assembly work of cathodes from starter sheets, conductive rods and hangers.

(2) TheS.S.cathodes have high strength and good flatness, which, together with the flattened anode plates, can shorten the distance between electrodes.

(3) The cathodes are of regular size and good flatness, thus reducing the chance of short circuits, allowing for higher current density and fewer operators for short circuit detection and handling.

(4) The cathode plate operation is simplified, creating conditions for shortening the cathode cycle, which reduces the backlog of Copper in production and speeds up capital turnover.
