20110017644 | Method and System for Separating and Recovering Like-Type Materials from an Electronic Waste System - Recovering like-type materials from an electronic waste stream. The recovered materials can include, without limitation, ferrous and non-ferrous metals and plastics. Also, printed circuit board materials and precious metals can be recovered. Distinct technologies are combined to achieve the separation of the unique materials. | 01-27-2011 |
20110024531 | Method and System for Separating and Recovering Wire and Other Metal from Processed Recycled Materials - 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. | 02-03-2011 |
20110067569 | Apparatus and Method for Separating Materials Using Air - Separating a mixture comprising at least two solid materials comprises transporting the mixture into a plenum, introducing air into the plenum, removing a heavier fraction of the solid materials from the plenum, removing air having a lighter fraction of the solid materials entrained therein from the plenum, removing the lighter fraction of the solid materials from the air that is removed from the plenum, filtering the remaining air, and re-circulating the air back to the plenum. Valves at the locations where material is introduced to and removed from the system can prevent air flow therethrough while allowing the materials to pass. The air can be introduced into the plenum at an angle with respect to the pathway in which the heavier fraction of the materials falls through the plenum, thereby avoiding damage to a screen that diffuses the air being introduced into the plenum. | 03-24-2011 |
20110147501 | Method and System for Separating and Recovering Wire and Other Metal from Processed Recycled Materials - 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. | 06-23-2011 |
20120199676 | Method for Separating and Recovering Concentrated Copper and Other Metal from Processed Recycled Materials - Processing waste materials to recover valuable metals, such as copper, from the materials. The disclosed methods employ processes that further refine the waste materials to concentrate the metallic material after the waste materials are initially processed. Processes include employing mechanical separation, air separation, sizing, and density separation. | 08-09-2012 |
20120260772 | Method and System for Processing an Iron Ore Tailings Byproduct - Methods and systems for processing an iron ore tailings byproduct are described. In one embodiment, a method for processing an iron ore tailings byproduct includes sizing particles within a slurry of the iron ore tailings byproduct to separate particles from the slurry having a dimension less than a predetermined size. After sizing, the method may further include centrifugating the particles less than the predetermined size into centrifugated concentrate and tails portions. The centrifugated concentrate portion may be separated into separated concentrate and tails portions. Finally, in certain embodiments, the separated concentrate portion may be de-watered to a remaining composition of matter comprising iron in greater proportion than in the iron ore tailings byproduct. Generally, using the systems and methods described herein, iron that would have otherwise been un-recovered is extracted from the iron ore tailings byproduct. | 10-18-2012 |
20130008832 | Method and System For Separating and Recovering Wire and Other Metal from Processed Recycled Materials - 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. | 01-10-2013 |
20140077008 | SYSTEM AND METHOD FOR IRON ORE BYPRODUCT PROCESSING - Processing byproduct material from a direct reduction process of iron ore to reclaim iron and other materials from the byproduct. The systems and methods employ gravity separation tables to separate the iron from other byproduct material constituents. The byproduct material constituents may be size reduced, processed to remove dust, and sized prior to processing by the gravity separation. | 03-20-2014 |
