    摘要： Processes for recovering coal from a particulate composite in which the composite is mechanically worked in the presence of an agglomeration promoting additive and in an aqueous carrier to effect a separation of the particles of coal in the composite from mineral matter associated therewith, a coalescence of the coal particles into product coal agglomerates, and a dispersion of the mineral matter in the aqueous carrier. The product coal agglomerates are resolved into their particulate constituents, and the latter are subjected to a density differential separation which effects a separation of that material in the agglomerates which has a relatively low mineral matter content and a high coal content from that having a higher content of mineral matter.

    摘要： The present invention is further directed towards a method for determining the efficiency of separation of a dense media separation process. This method includes determining an apparent distance a particle must travel in a dense media cyclone to be correctly beneficiated. From this apparent distance, an apparent velocity a particle must achieve to be correctly beneficiated is calculated. This apparent velocity is used, along with cyclone geometry and operational parameters to calculate a divergence value which indicates the efficiency of separation. The present invention also includes a method for selecting cyclone geometry and operating parameters which includes determining separation efficiency and adjusting geometry and parameters in a manner to obtain improved efficiency.

    摘要： Fine particle coal is beneficiated in specially designed dense medium cyclones to improve particle acceleration and enhance separation efficiency. Raw coal feed is first sized to remove fine coal particles. The coarse fraction is then separated into clean coal, middlings, and refuse. Middlings are comminuted for beneficiation with the fine fraction. The fine fraction is deslimed in a countercurrent cyclone circuit and then separated as multiple fractions of different size specifications in dense medium cyclones. The dense medium contains ultra-fine magnetite particles of a narrow size distribution which aid separation and improves magnetite recovery. Magnetite is recovered from each separated fraction independently, with non-magnetic effluent water from one fraction diluting feed to a smaller-size fraction, and improving both overall coal and magnetite recovery. Magnetite recovery is in specially designed recovery units, based on particle size, with final separation in a rougher-cleaner-scavenger circuit of magnetic drum separators incorporating a high strength rare earth magnet.

    摘要： Raw coal, which contains coal and waste, is introduced into a sizing box having vertically spaced screens inclined rearwardly with the screens being vibrated to separate particles below a selected size from the raw coal. Raw coal is introduced into a washer box, which has a medium therein of a selected specific gravity to cause coal below a specific gravity to float to the top of the medium so as to be separated from the waste with the waste, which is of heavier specific gravity, falling to the bottom of the washer box. The medium and the separated coal therein flow along an inclined trough to a vibrating shaker, which has a plurality of vertically spaced screens inclined rearwardly. When flowing along the trough, at least half of the medium returns to a sump from which it is supplied by a pump to the washer box to maintain a desired level of the medium so that the medium will continuously flow from the washer box along the trough to the shaker. Compressed air is supplied above each of the screens in both the sizing box and the shaker with the compressed air in the sizing box helping to separate the particles from the raw coal. In the shaker, the compressed air removes some of the medium from the particles of coal. Pressurized water also is supplied to the shaker to aid in removing the remaining medium from the coal particles, which are discharged to a conveyor.

    摘要： The present invention relates to a process for separating scrap essentially consisting of non-ferromagnetic metals into several fractions by specific gravity in which only one heavy separating medium is required. The scrap has been recovered from waste products composed of metals and non-metals by reducing the particle size of the waste through grinding to a size less than 50 mm including particles as small as 0.5 mm. Thereafter, the ferromagnetic components are magnetically separated from the ground waste and the ground waste is fed to a primary specific-gravity separator where non-metallic components are separated from the non-ferromagnetic portion of the ground waste. Thereafter, further separation of the non-ferromagnetic portion in a secondary and, in some cases, tertiary separators is accomplished.
