Abstract: Processing waste materials to recover valuable metals, such as copper, from the materials. Waste materials are further refined 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.

Abstract: Devices, systems, and methods for recovering metal constituents from a waste stream containing metals (e.g., incinerator ash) are described. The waste stream may include incinerator bottom ash, fly ash, or a combination thereof. A falling velocity separator is employed in combination with a centrifuge to separate and collect metals from the waste stream. The falling velocity separator uses a liquid to separate particles within incinerator ash according to the particles settling velocities. The centrifuge further separates particles from the incinerator ash according to density of the particles.

Abstract: 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.

Abstract: Processing excavated ASR from an ASR landfill. The processing includes excavating the ASR and co-mingled material, sizing the excavated material, separating the excavated, sized material into a heavy and light fraction, and further processing the heavy fraction to recover ferrous and non-ferrous metals.

Abstract: Processing automobile shredder residue (ASR) zorba to separate aluminum and magnesium from the other non-ferrous metals. The system and method employs a destoner to separate the magnesium and aluminum from other non-ferrous metals in the ASR zorba. The resulting magnesium and aluminum product may be further processed by a destoner to separate the aluminum from the magnesium. The ASR zorba may be segregated by size prior to processing in the destoner.

Abstract: Processing shredder residue fines to recover valuable metals, such as copper, from waste 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 a destoner, and optionally multiple destoners and screens, to concentrate metal constituents in the shredder residue fines.

Abstract: Processing copper wire concentrate produced from processing ASR to generate a bare copper product. The disclosed systems and methods employ processes that remove constituents from the copper wire concentrate that can damage conventional chopping equipment. After removing the constituents that can damage conventional chopping equipment, the process employs a grinder to grind the remaining copper wire to liberate the bare copper metal from the insulation material.

Abstract: A method for processing low grade iron ores includes a step of receiving iron ore tailings. The method further includes separating the iron ore tailings into two or more groups based on sizes of the iron ore tailings. Each group includes a respective portion of the iron ore tailings. The method also includes processing the portion of the iron ore tailings in at least one group using a density separation process to generate iron ore concentrate.

Abstract: 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.

Abstract: 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.
