1. Project Name: Research and Application of Key Technologies for Green and Quality-preserved Recycling Manufacturing of Scrap Copper Resources

2. Project Overview

This project belongs to the field of recycled metal resource circulation and utilization. It was approved and initiated by the Ningbo Science and Technology Bureau in September 2013, with project number 2013B10005. The project is undertaken by Ningbo Changzhen Copper Industry Co., Ltd., with collaboration from Suzhou Nonferrous Metals Research Institute Co., Ltd., and the research period is from January 2013 to December 2014. Using scrap copper as raw material, the project systematically studied technologies such as refined preprocessing of scrap copper, special refining agents, and smelting processes. Advanced technologies like iron removal refining agents and their refining process, tandem parallel smelting furnaces, automated mechanical ramming and stirring were developed. A production line for recycling copper resources was established, forming a large-scale production capacity for recycled copper products. After testing by Zhejiang Metallurgical Product Quality Inspection Station Co., Ltd. and Ningbo Product Quality Supervision and Inspection Institute, the technical indicators met relevant standard requirements. Users reported satisfactory performance, demonstrating significant economic and social benefits. The project has obtained 22 patent results, including 7 invention patents, and participated in formulating 4 national and industry standards.

5. Promotion and Application Status, and Social Benefits

In the "13th Five-Year" Development Plan for the Renewable Non-ferrous Metals Industry (draft), technological innovation and main tasks have mentioned: giving priority to the development of fine sorting, pretreatment, and grade-preserving utilization technologies for non-ferrous metal scrap; focusing on the value-preserving utilization of scrap copper, and using scrap copper as raw material to produce high-value electronic materials, electrical materials, fine products, high-precision castings, green copper alloy products, etc. This project directly utilizes scrap copper to produce high-precision copper alloy processed materials that have strong market demand and good development potential, which aligns with national industrial policies and promotes the development of the recycled copper industry, with promising market prospects.

This project converts scrap copper directly into high-precision, environmentally friendly, and free-cutting brass materials, efficiently and qualitatively utilizing limited renewable resources. It not only solves the problems of insufficient resource supply and the comprehensive utilization of "urban mines", but also provides the society with the required high-precision, environmentally friendly copper alloy materials. Additionally, it addresses issues of high energy consumption and pollution, avoiding the oxidation loss of zinc and other valuable metals and the subsequent exacerbation of environmental pollution. It boasts significant economic and environmental benefits. The recycling and reuse of scrap copper have a positive energy-saving and emission-reduction effect on society, contributing to the energy-saving efforts of China's non-ferrous metals industry. This project directly utilizes scrap copper to produce high-quality, high-value-added, and easily processable high-precision copper materials for downstream industries such as automotive parts, fire-fighting equipment, valve core, communication equipment, refrigeration components, electrical appliances, electronics, plumbing, hardware accessories, etc., providing high-quality copper alloy basic materials. Amidst the current overall economic downturn in the non-ferrous metals processing industry, this project promotes "machine substitution" in downstream enterprises, provides raw material support for their transformation and upgrading, and achieves a win-win situation for both enterprises and customers.
