Abstract: The present invention relates to a gravity/flotation circuit where a mineral stream, such as a flotation rougher or cleaner concentrate, undergoes a two stage size separation wherein: i) the screen of the first stage provides a coarse stream of particles greater than 110 microns and a fines stream of particles less than 110 microns; and ii) the fines stream of less than 110 microns is subjected to the second stage separation whereupon a cyclone provides an ultrafine/slimes stream of p80 less than about 25 microns and a middlings stream of p80 greater than around 25 microns.

It has been discovered that a large proportion of the MgO minerals in the concentrate are contained in the 30 to 100 micron size fraction and that they are well liberated making physical separation possible.

Abstract: A device for separating particles according to their respective masses includes a substantially cylindrical wall of inner radius, “Rwall”, that surrounds a chamber and defines a longitudinal axis. A multi-species plasma having relatively cold ions is initiated at a first end of the chamber within a relatively small radius, “rsource”, from the longitudinal axis.

After reaching apogee, these ions lose energy and strike the cylinder where they are collected. Low mass ions are placed on small radius helical trajectories and pass through the hollow cylinder.

Abstract: A device for separating high mass to charge particles (M1) from low mass to charge particles (M2) in a plasma includes a cylindrical wall that surrounds a chamber and defines an axis. Rectangular shaped coils are mounted on the wall to establish a magnetic field, B0, in the chamber that is aligned substantially perpendicular to the axis and which rotates about the axis. Circularly shaped coils are provided to generate a time-constant, axially aligned magnetic field, Bz, in the chamber. Passive, ring-shaped electrodes are positioned at the ends of the wall and connected to resistors which are then grounded. The rotating magnetic field, B0, rotates the plasma in the axially aligned magnetic field, Bz, which in turn, induces a radially oriented electric field, Er, in the chamber. The crossed fields (i.e. Er×Bz) cause the particles, M1, to strike the wall while the particles, M2, transit through the chamber.

Abstract: An insulation box unit and a refrigerator of the present invention employs i) rigid urethane foam with a 8.0 MPa-or-greater bending modulus, and a 60 kg/m3-or-lower density, and ii) a vacuum insulation material. The proper bending modulus provides the insulation box unit with a substantial strength, even in the case that the coverage of the vacuum insulation material with respect to the surface of the outer box exceeds 40%. The proper density prevents the insulation box unit from poor insulation efficiency due to undesired solid thermal conductivity. Despite of an extended use of the vacuum insulation material, the insulation box unit offers an excellent insulation efficiency and therefore accelerates energy saving. According to the recycling method of the present invention, rigid urethane foam formed of tolylene di-isocyanate composition, which was separated from refrigerator wastes, is recycled as a material of rigid urethane foam.

Abstract: An isotope separator includes a cylindrical chamber having first and second ends, and a length “L.” Inside the chamber, an E×B field is applied to produce plasma rotation. The energy in the plasma rotation is chosen to be much higher than the electron temperature which is clamped by radiation. As the plasma then transits the chamber through the length “L”, the electrons cool the thermal temperature of the isotope ions while maintaining the rotation. Under these conditions, the minority and majority isotopes become substantially separated from each other before they exit the chamber. To achieve this result, E×B is determined using mathematically derived expressions and, in compliance with these parameters, the length “L” of the chamber is determined so that the plasma residence time in the chamber, &tgr;1, will be greater than the cooling time, &tgr;2 (&tgr;1>&tgr;2) necessary to affect isotope separation.

Abstract: A high throughput plasma mass filter includes a substantially cylindrical shaped plasma chamber with structures for generating a magnetic field (B) that is crossed with an electric field (E) in the chamber (E×B). An injector introduces into the chamber a multi-species plasma having ions of different mass to charge ratios. To obtain high throughput (&Ggr;), the initial density of this multi-species plasma is considerably greater than a collisional density wherein there is a probability of “one” that an ion collision will occur within a single rotation of the ion under the influence of E×B. The length of the chamber is chosen to insure heavy ions can make their way to the wall before transiting the device.

Abstract: A device and method for selectively establishing predetermined orbits, relative to an axis, for ions of a first mass/charge ratio (m1), requires crossing an electric field with a substantially uniform magnetic field (E×B). The magnetic field is oriented along the axis and the electric field has both a d.c. voltage component (∇&PHgr;0) and an a.c. voltage component (∇&PHgr;1). In operation, voltage &PHgr;0 is fixed to place the ions m1 on confined orbits around the axis when &PHgr;1 is zero. On the other hand, when &PHgr;1 is tuned to a predetermined value, the ions m1 are ejected away from the axis. With E×B established in a chamber, the ions m1 will pass through the chamber when on confined orbits (&PHgr;1=0), and they will be ejected into the wall of the chamber when on unconfined orbits (&PHgr;1=predetermined value).

The trapped metal ions are then removed with the molten salt from the chamber.

The light material stream is passed under a cross belt magnetic separator where the light ferrous metals are separated. The remaining light material stream is conveyed to a rotary trommel which separates the light material stream into two fractions based on size, with the fine material becoming relatively inert through processing and being used as a cover material for landfills.

Coil(s) and electrode(s) are provided to establish crossed electric and magnetic fields within the wave guide to separate plasma ions according to their mass. A circularly polarized electromagnetic wave having specific characteristics is launched through a first end of the wave guide and into the plasma to generate ponderomotive forces on the plasma particles via photon reflection.

This structure allows feed plasma to be continuously introduced into the first end of the wave guide for separation therein. A resonance cavity is provided to redirect the reflected photons back into the plasma.

Abstract: A system and method for separating solids from a fluid environment is provided. The system includes a device having housing with a substantially cylindrical upper portion and a substantially conical lower portion. The device also includes a chamber at an intersection between the upper portion and the lower portion, and an inlet in communication with the chamber for generating a cyclonic flow pattern into the conical lower portion. As the cyclonic flow with a suspension of solids is introduced into the lower portion, the flow decreases in velocity. Thereafter, the flow rises within the conical lower portion at a velocity less than the settling velocity of the solids, generated by gravitational forces, thereby resulting the separation of the solids from the fluid. The ascending fluid substantially free of solids can be collected through an upper portion, while the settled solids can be collected towards an apex of the conical lower portion and subsequently removed.
