Abstract

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.

Claims (16)

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.
2. The method of claim 1 further comprising the step of screening the non-ferrous metal stream fraction generated at step d to separate the stream into a first size fraction and a second size fraction.
3. The method of claim 2 wherein the first size fraction comprises material that is processed with a dynamic sensor.
4. The method of claim 2 wherein the second size fraction comprises material processed in a second vacuum pressure separator to further concentrate the non-ferrous metal.
5. The method of claim 4 wherein the second size fraction is size reduced prior to processing in the second vacuum pressure separator.
6. The method of claim 5 wherein the second size fraction is size reduced using a crusher.
7. The method of claim 1 wherein the non-ferrous metal comprises copper.
8. The method of claim 1 wherein the waster stream comprises processed automobile shredder residue.
9. A method for processing a waste stream comprising the steps of:

a) receiving the waste stream comprising non-ferrous metal components;

b) processing the received waste stream with an air separator to generate a light fraction waste stream and a heavy fraction waste stream;

c) removing ferrous material from the first heavy fraction waste stream to concentrate the fraction of non-ferrous metal in the first heavy fraction;

d) separating the first heavy fraction resulting from step c into a first size fraction and a second size fraction, wherein the size of the first size fraction is smaller than the second size fraction;

e) mechanically reducing the size of the first size fraction; and f) processing the material resulting from step 3 with a vacuum pressure separator to further concentrate the non-ferrous metal.
10. The method of claim 9 wherein the light fraction from step b) comprises #2 copper.
11. The method of claim 9 wherein the step of mechanically reducing the size of the first size fraction comprises using a crusher to crush the first size fraction.
12. The method of claim 9 wherein the second size fraction is further processed by a dynamic sensor.
13. A system for processing a waste stream comprising:

a plurality of metal concentration facilities, wherein each concentration facility is located in a geographic location different from each of the other metal concentration facilities in the plurality of metal concentration facilities, wherein each metal concentration facility comprises:

a metal waste stream separator using air to separate the waste stream into a light fraction and a heavy fraction, wherein the heavy fraction comprises a concentration of non-ferrous metal as compared to the concentration of non-ferrous metal in the metal waste stream;

a vacuum pressure separator that further concentrates the non-ferrous metal fraction in the heavy fraction; and a single metal concentrate processing facility operable to process non-ferrous metal concentrate from the plurality of metal concentration facilities to further concentrate the non-ferrous metal concentrate.
14. The system of claim 13 wherein the single metal concentrate processing facility comprises a dynamic sensor to further concentrate the non-ferrous metal concentrate.
15. The system of claim 13 wherein the single metal concentrate processing facility comprises a vacuum pressure separator to further concentrate the non-ferrous metal concentrate.
16. The system of claim 13 wherein the metal waster stream processed by the metal waste stream separator using air comprises processed automobile shredder residue.
