Key innovations
The innovation of this technology lies in the adoption of leading low-acid catalytic oxidation process to efficiently extract 99.999% high-purity pure copper, and the ability to customize equipment to realize the resource utilization of waste circuit boards and economic and environmental protection benefits.
Potential economic benefits
This technology achieves high-value resource regeneration by extracting more than 99.999% of high-purity precious metals such as copper and gold from used circuit boards. Low-pollution processes reduce environmental costs. This move turns waste into treasure, solves corporate waste treatment problems, and significantly improves the economic benefits and profitability of resource recycling companies.
Potential climate benefits
Recycling scrap copper replaces primary production, significantly reducing mining and smelting energy consumption and carbon emissions. Low-pollution processes reduce the carbon footprint of environmental treatment.

Solution details

The technical attribute of this project is new process.

(1) Extraction of metallic copper from waste circuit boards. The purity of copper can reach more than 99.999%, and the technology is ahead of domestic counterparts;

(2) The leaching of copper uses a low-acid and low-pollution catalytic oxidation method, which is environmentally friendly and feasible;

(3) The equipment required for the entire process is designed by itself and can be designed according to specific conditions.

Application situation or application prospects：The project has been successfully applied to a resource recycling enterprise, which is mainly committed to the recycling of used household appliances. Before the implementation of the project, the company mainly focused on sorting and recycling after dismantling, and a large number of circuit boards could not be processed; after the implementation of the project, while the circuit boards were processed, valuable non-ferrous and precious metals such as copper and gold in the waste circuit boards were extracted., processing waste while producing considerable economic benefits.
