| 20080302706 | Method For Separation of Heterogeneous Products, Including Household Waste - A method for separation of heterogeneous products included in household waste (HW) comprises separating the products in a fractionation vessel containing a liquid. The waste includes components, of which at least some are capable of floating in the liquid. The components are exposed to a first essentially horizontal force (P1) in a first direction (D1) enforced by a flow of the liquid in the fractionation vessel and to a second essentially horizontal force (P2) in a second direction (D2), which is substantially different from the first direction (D1). The combined impact of the forces (P1; P2) on the components spreads the components and leads them to at least two collection areas. Products of varying buoyancy may thus be treated separately. | 12-11-2008 |

| 20090065404 | PROCESS FOR RECLAIMING MULTIPLE DOMAIN FEEDSTOCKS - A process for the separation of a multiple domain solid feedstock such as that derived from ASR, WSR, and/or ESR is disclosed which comprises granulating the feedstock to produce particles each of substantially a single domain, with each type of particle having a different density. The particles are introduced into a suitable aqueous salt solution. Aqueous salt solutions containing cations comprising sodium, calcium and ammonium, and anions comprising nitrate, bromide, and chloride are useful. A dispersion mixer having a high shear and/or turbulent zone is utilized to disperse agglomerated particles and a quiescent hydrogravity tank is utilized to effect binary separation of the mixture of particles into a stream with a higher average specific gravity, and a stream with a lower average specific gravity. A higher degree of product purity can be obtained by subjecting either of the product streams from the first hydrogravity stage to additional stages of hydrogravity separation. Froth flotation may be used to further separate particles of similar specific gravity but different chemical composition. | 03-12-2009 |
| 20090255855 | APPARATUS AND METHOD FOR SEPARATING MATERIALS - A material separator for separating at least two different materials of differing densities and/or sizes of particles. The material separator generally includes a tank containing a flocculent, a circulation system for circulating flocculent within the tank and a pair of conveyors for moving two different materials out of the tank. The tank may include an upper chamber and a lower chamber. At least a portion of each of the conveyors is located in the upper chamber to catch materials fed into the flocculent. Each of the conveyors may include a mesh belt that permits the flocculent to flow through the conveyor. The tank may include a clean out valve that permits fines and other debris accumulated within the upper chamber to pass into the lower chamber. The flocculent circulation assembly may include a nozzle that can be constructed in various configurations to create flows of flocculent of various velocities and trajectories. In one embodiment, the lower chamber includes a drag line assembly that removes fines and other accumulated debris from the lower chamber. | 10-15-2009 |

| 20110155652 | METHOD OF SOLID FUEL BENEFICIATION AND TRANSPORTATION TO THERMOELECTRIC POWER STATIONS - The invention relates to mining of fossil energy minerals and can be applied to the beneficiation and utilization of various kinds of coal and shale oil as a solid fuel for thermoelectric power stations. The object of the invention is to reduce the energy consumption of mining energy generation, to eliminate solid fuel loss, to reduce water consumption and to protect the environment. To this end, the beneficiation process is performed underground, in the immediate proximity to the place of beneficiation waste stowing, using aqueous salt solution with a density intermediate between those of the target component and waste rock. The regeneration of heavy liquid from final beneficiation tailings is performed by washing with non-aqueous volatile liquid, with subsequent drying by the subsurface heat after placing these tailings in the worked-out space. The resulting vapors are compressed and condensed; thus regenerated non-aqueous liquid is returned for washing the beneficiation tailings, while effluents produced by washing are separated into aqueous and non-aqueous components by heat released at the liquefaction of the non-aqueous liquid vapors. The enriched solid fuel remaining in the floatable state is delivered by its flow to the thermo-electric power plant, where it is separated hydromechanically from liquid component, washed with water, dried and directed to combustion. The effluents from washing with water are evaporated with heat released at the condensation of the working medium of the power station thermodynamic cycle. Then they are mixed with drains from solid fuel delivered to the destination, and returned to the starting point of the process. | 06-30-2011 |
