摘要： An apparatus including a screen capable of separating solids from a liquid-solid mixture and a first probe disposed beneath the screen. The first probe is provided to determine a position of a beach between the liquid-solid mixture and separated solids. The apparatus may measure a property of a local volume of a probe disposed beneath a first separator deck. The probe may then send a first signal to database. Based on the signal a location of a beach may be determined.

摘要： A method is disclosed for the separation of oil shale from run of mine (ROM) oil shale containing particles of oil shale and refuse, which comprises conditioning the ROM oil shale with a coupling agent capable of selectively coating the kerogen hydrocarbons in the particulate oil shale to the substantial exclusion of coating the non-hydrocarbonaceous refuse, which coupling agent is one or more compounds selected from the group consisting of an alcohol, at least one carboxylic acid, preferably containing from about 5 to about 28 carbon atoms and a ketone. Combined with said coupling agent is a fluorescent dye in a quantity to make the coated particles of oil shale fluoresce upon excitation to a degree sufficient to distinguish the coated oil shale particles from the substantially non-coated refuse. Exciting (e.g. as with ultraviolet light) the fluorescent dye coupled to the oil shale particles induces fluorescence and enables separating the fluorescing, coated oil shale particles from substantially non-fluorescing, non-coated refuse particles.

摘要： The present invention provides a method and an apparatus for separating a mixture that are capable of separating a mixture containing a plurality types of particles, using a countercurrent classification technique, even when there is little difference in density and particle diameter depending on the types of particles. In the present invention, a mixture containing first particles and second particles is separated using a separation tube 13 having the inverted-conical or pyramidal shape or a substantially inverted-conical or pyramidal shape. The first particles and the second particles are made of substances having different magnetic susceptibilities. A fluid is caused to flow upward through the separation tube 13, and the flow of the fluid is used to introduce the mixture into the separation tube 13. The first particles and the second particles are held in the separation tube 13 in a mixed state. A gradient magnetic field is applied to a region inside the separation tube 13 using magnetic field generation means 23, in the state where the first particles and the second particles are held in the separation tube 13. The magnetic field gradient of the gradient magnetic field has a vertical component.

摘要： A ferrofluid sink/float separator for separating nonmagnetic materials of different densities comprises a horizontal separating tank and a magnetic field generating mechanism. The separating tank is filled with a ferrofluid capable of being induced by the magnetic field generating mechanism to have a magnetic field gradient and various apparent densities in the direction of earth gravity. The magnetic field generating mechanism comprises two magnetic poles spaced at an interval and a gap which is defined by the two magnetic poles and is located under the horizontal separating tank.

摘要： Apparatus and method for sorting scrap metal pieces dependent on the type of metal therein. The apparatus includes a conveyor and a feeding arrangement to feed the scrap metal pieces on to the conveyor, together with an X-ray fluorescence detector to examine each metal piece and determine the type of metal as a result of the characteristic X-rays emitted. A respective control signal is utilized to move pegs on the conveyor so as to permit the respective metal piece to exit from the conveyor along a respective path and to enter a bin for that particular type of metal. In this way scrap metal pieces of different metal are collected in different bins for subsequent processing.
