Abstract:
A method for recovering metals from waste in which material is roughly or coarsely separated to leave a fibrous feedstock, the feedstock is comminuted with a mill (e.g., a ball mill) to liberate and separate the fibrous feedstock to obtain a mix of a metal fraction and residue, and the metals fraction and the residue are collected. There is a system employing the same to treat such materials.
Abstract:
A fluidized inertia table for separating materials between an upstream delivery station and a downstream receiving station is provided. The fluidized inertia table for separating materials creates a moment of inertia and/or rotary motion which are then translated into reciprocating or jarring motions and separates the materials loaded onto the tray.
Abstract:
An apparatus/system for separating a mixture of solid materials has a screening bed, an expansion chamber in gaseous communication with the screening bed, a filter in gaseous communication with the expansion chamber, an air flow producer in fluid communication with the filter. The screening bed includes a star-shaped agitators and the air flow is a vacuum from the screening bed through pathway.
Abstract:
A system and method for recovering metals from a waste stream includes or uses a feeder, a first screw separator, a slurry tank, and a second screw separator configured to receive carrier fluid and particles from the slurry tank. The method and system can include feature to improve water usage.
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.
Abstract:
An automated system for sorting dissimilar materials, and in particular for sorting plastics from other materials and for sorting different types of plastics from one another comprises, depending upon the embodiment, combinations of a sizing mechanism, a friction separation, an air separator, a magnetic separator, a dielectric sensor sortation bed, shaker screening, a ballistic separator, an inductive sensor sortation system and a float/sink tank. The dielectric sensor sortation system may be either analog or digital, depending upon the particular implementation. One or more float/sink tanks can be used, depending upon the embodiment, each with a media of a different specific gravity. The media may be water, or water plus a compound such as calcium chloride. In addition, multiples of the same general type of module can be used for particular configurations. A heavy media system or a sand float process can be used either alternatively or additionally.

Abstract:
Recovering metallic materials, such as copper, from waste materials. The A dynamic sensor measures the rate of change of current generated by metallic materials in the waste materials. Preprocessing and post processing of the waste materials may be completed to further concentrate the amount the metallic materials recovered from the waste.
Abstract:
A method, apparatus and system for sorting contaminated glass from a stream of glass particles used light of a wavelength suited to inducing fluorescence in the contaminated glass pieces. Automatic cleaning mechanisms are included in some embodiments to facilitate removal of coatings which would prevent the contaminated particles from fluorescing. The identified particles are then automatically separated from the remaining particles.
Abstract:
Processing metallic materials, such as copper, from waste materials. The systems and methods employ a dynamic sensor, which measures the rate of change of current generated by metallic objects that pass by the sensor to identify metallic objects in a waste stream. The dynamic sensor may be coupled to a computer system that controls a material diverter unit, which diverts the detected metallic objects for collection and possible further processing. The systems or methods may employ stages of sensors for sequential recovery of materials.
