Method and system for separating and recovering wire and other metal from processed recycled materials

摘要

Processing waste materials to recover valuable metals, such as copper, from the materials. The disclosed systems and methods employ processes that further refine the waste materials to concentrate the metallic material after the waste materials are initially processed. Processes include employing air separation and screening. Processes also include employing a dynamic sensor and a vacuum pressure separator to separate metals from other materials. A central processing facility may process metal concentrate from multiple concentration facilities.

1. A method for processing a waste stream comprising the steps of:
a) receiving the waste stream comprising non-ferrous metal; b) processing the received waste stream with a closed-loop air separator to separate the waste stream into a light fraction waste stream and a heavy fraction waste stream; c) processing the heavy fraction waste stream in a vacuum pressure separator to increase the concentration of non-ferrous metals in the heavy fraction waste stream as compared to the concentration of non-ferrous metal in the waste stream; and d) separating the heavy fraction stream resulting from step c into a ferrous metal stream fraction and a non-ferrous metal stream fraction by removing any ferrous metal from the heavy fraction stream resulting from step c.
