Driven by carbon neutral targets and high-end manufacturing needs, the global copper
electrolysis industry is undergoing a deep transformation. Facing the urgent demand for
99.997% ultra-high purity copper materials in new energy, electronic information and other
fields, the traditional impurity treatment process has shown fatigue. Intelligent copper
particle automatic cleaning technology, with its subversive innovation, is reconstructing
the economic model of copper electrolytic production and environmental standards,
becoming the core of the industry transformation and upgrading.
The technological inflection point of copper electrolysis clean production
The annual global copper electrolysis production exceeds 28 million tons, but the industry is facing serious challenges:
Environmental protection costs are surging: the traditional process produces 3-5kg of copper-containing sludge per ton of
copper, and the cost of hazardous waste treatment accounts for more than 12% of the processing fee;
Quality bottleneck highlights: the surface roughness of copper foils used in new energy automobiles is required to be
<1.2 μm, and the rate of the existing process meets the standard is less than 65%;
The constraints on energy consumption are being tightened: The EU carbon tariff will include electrolytic copper in the
scope of taxation, China's “Industrial Energy Efficiency Improvement Plan” requires an 8% drop in electricity consumption
per ton of copper in 2025.
According to the estimation of International Copper Study Group (ICSG), intelligent impurity treatment technology can
reduce the comprehensive cost of electrolytic copper by 18-25%, which drives the global major copper enterprises to
accelerate the technology iteration.
Three Innovative Dimensions of Intelligent Cleaning Technology
1. Holographic Upgrade of Sensing System
New-generation Intelligent Cleaning Device integrates multimodal sensing technology:

Measurement of a 200,000-ton project shows that the new technology improves the surface finish of copper cathode by
40% and reduces steam consumption by 1.2GJ per ton of copper.
3. Intelligent leap in control system
Artificial intelligence algorithms are integrated into the closed-loop of production in depth:
