摘要： A process and apparatus for subjecting a mixture of two types of electrically charged particles to intense physical contact through a pneumatic transfer modified by turbulent flow and path interruptions to produce surface electrical charges on the particles, and separating the charged particles to recover particles having the same charge. Seeding with a recoverable catalyst may be used as well as forming the path of the mixture from one of the two types of electrically neutral particles. The path interruptions may be sudden directional changes, circuitous paths, baffles, induced vortices and other mechanical apparatus.

摘要： A method for separating components of a mixture containing particles which can be electrically charged from particles which can be only negligibly charged is disclosed. The mixture is fed onto an electric undulating traveling wave contact panel which is energized to a charging potential using A. C. voltage. The voltage is then increased to a separation voltage to effect levitation and movement of the charged particles away from the uncharged particles. Separation is accomplished by cycling the voltage between the separation and charging voltages until the charged particles are moved off the panel and the uncharged particles remain on the surface of the panel. The separated particles can then be collected separately.

摘要： Calcined trona and/or nahcolite bearing ore particles are separated into a plurality of fractions of relatively uniform particle size. Those calcined particles smaller than about 6.7 mm in size and larger than about 0.2 mm in size are passed through an electrostatic separator to obtain an ore concentrate containing a greater percentage of soda ash and a lesser percentage of insoluble impurities than were present in the ore; a middling fraction and an ore tailing fraction containing a lesser percentage of soda ash and a greater percentage of insoluble impurities than were present in the ore. The middling fraction may be recycled to increase the yield of ore concentrate. Calcined particles smaller than about 0.2 mm may be combined with the ore concentrate. The combined ore concentrate fraction may be marked as technical grade soda ash or used as a high grade feed to a monohydrate refining process.

摘要： A method and apparatus for classifying desirable particles of powder metal by size and removing particles of undesirable material of a different density than the metal particles. There is included a housing defining a closed flow path for a recirculated stream of protective gas different than ambient air. A particle supply device introduces particles into the housing at a controlled rate in a downwardly falling stream. A plurality of receptacle trays are disposed in the housing generally vertically below the particle supply device with each tray having a forward lip positioned forwardly in the direction of the gas flow of the trays thereabove. An electrostatic gas ionizer is disposed upstream of the particle supply device for ionizing the gas and a screen is disposed in the stream of gas between the ionizer and the particle supply device for attracting the ionized gas from the ionizer while allowing the passage of the gas through the screen for establishing the recirculated stream of gas to impinge the stream of falling particles to impart to each particle a horizontal component of velocity so that the trajectories of the particles will vary depending upon size and density thereof for falling into the various receptacle trays. Consequently, the desirable particles are classified by size, undesirable particles of a different density than the desirable particles are removed or separated out, undesirable hollow particles are also removed or separated out, and because of the charge placed thereon, clusters of particles are broken up, i.e., the particles in such a cluster repel one another and separate.
