Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. Shredded matter, or ASR, is sent through a series of sorters before reaching a system that separates out copper bits. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper.

Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper wire bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper. A secondary copper recovery conveyor having a field of nails or spikes may be added subsequent to the last primary conveyor for enhanced yield of copper wire.

The invention is intended for integrated decontamination of soils contaminated with mercury (amalgam) or/and radionuclides. Method for soil decontamination includes preparation of pulp by mixing soils with water at the soil sampling point with separation of fraction with fragments more than 100 mm in the pulp preparation module, disintegration of pulp and soil aggregates in the disintegration module with separation of plants residues and fraction with fragments more than 10 mm. Pulp thickening. In the hydroclassification module the pulp is separated into sand and fine particle fractions, the fine particle fraction goes to the dehydration module, designed as a concentrator, where it is thickened and dehydrated for further disposal. If mercury and amalgam are present in soils they are separated in the thickening module. Technical resultimplementation of a low-waste nonchemical technology for decontamination of soil from mercury, its water-insoluble forms, amalgam or/and radionuclides in a single technological process without equipment resetting, separation of metal mercury or its amalgam.

The solid-liquid separator that uses the substance A capable of dissolving water and oil, and performs dehydration and deoiling from an object to be treated by bringing a mixture of water and a solid, oil and a solid, or water, oil and a solid that is an object to be treated, and the substance A in a liquid state into contact with each other, and subsequently evaporating the substance A, includes a substance B that circulates while causing change of state in a closed system, a compressor that compresses the substance B, a first heat exchanger that exchanges condensation heat of the substance B and evaporation heat of the substance A, an expansion valve that decompresses the substance B which is condensed, and a second heat exchanger that exchanges evaporation heat of the substance B and condensation heat of the substance A.
