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 result—implementation 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.

A method for treating composite materials of aluminum and plastics mixes the composite materials in a working area of a processor under high shear forces with a spiral in order to remove the aluminum layer from the plastic layer and to suspend it. The particles which are separated by a screen from the working area are treated in a hydrocyclone in order to separate aluminum from the liquid, wherein fibers present in the underflow are fed back with the liquid to the processor.

Disclosed are systems and methods for refractory recycling that result in refined individual refractory components from a network of aggregate refractory components based on a fragmentation process. In one embodiment, a network of refractory aggregates is crushed and deposited into a refiner machine. The refiner machine includes a blast chamber that houses a projecting mechanism. The deposited aggregate material is propelled from the projecting mechanism at a critical velocity. Upon impact with an inner lining of material within the blast chamber, contaminant particles can fracture apart from the deposited aggregate material, leaving a refined individual refractory component.

A method of separating different constituents of a fine fraction that is produced in a prior method for separating a concrete for deconstruction. The method allows the reuse of these different constituents in the production of a new cement and/or of a new concrete, the fine fraction including sand and at least 30% by mass of hydrated cement paste.

A method of processing a heterogeneous material includes entraining heterogeneous particles into a fluid stream. Each of the heterogeneous particles comprises a liquid portion and a solid portion. The fluid stream is passed through at least one adjustable nozzle, and is impacted to dissociate the liquid from the solid. A method of separating oil from solid particles includes mixing oil-coated solid particles with water to form a slurry, passing a first portion of the slurry through a first nozzle, and passing a second portion of the slurry through a second nozzle such that the second portion of the slurry intersects the first portion of the slurry to separate the oil from the particles.
