| 20080230447 | Method and Apparatus For Froth Washing in Floatation - A method and apparatus for introducing wash water into a flotation froth in a flotation separation system, where the wash water is injectioned into the froth in the form of a horizontal sheet of water. The sheet is typically formed by impinging a downwardly directed liquid jet issuing from a nozzle onto a horizontal plate or disc where it changes direction and travels radially outwards as an axi-symmetric planar liquid jet or sheet. The depth of the disc can be adjusted by a support rod. Other embodiments are described where the horizontal sheet is ejected through a horizontal slit, or where the sheet of wash water is rectangular rather than axi-symmetric. | 09-25-2008 |
| 20100193408 | METHOD AND APPARATUS FOR FLOTATION IN A FLUIDIZED BED - Separation of hydrophobic particles from a mixture of particles in a fluid is performed by providing a fluidized bed as a relatively non-turbulent contacting mechanism in a flotation cell incorporating a settling chamber located immediately above the fluidized bed. Hydrophobic particles attach to bubbles in the fluidized bed and rise to the interface with the settling chamber where non-hydrophobic particles flow over the lip of an internal launder and are removed as tailings at. The hydrophobic particles attached to bubbles float upwardly in the relatively placid settling chamber where unwanted gangue can fall back to interface. The bubbles form a froth layer at the upper surface of the settling chamber, and flow over the launder lip carrying the hydrophobic particles. An operation of the apparatus is kept stable by recirculating fluid from the settling chamber via pip and pump to mix with new feed entering at duct. | 08-05-2010 |

| 20120061298 | IMPROVED METHOD AND APPARATUS FOR FROTH FLOTATION IN A VESSEL WITH AGITATION - A method of separating mixed particles in a flotation cell uses a fluidized bed within the cell where particles are fluidized in a quiescent zone by liquid moving upwardly through the fluidized bed. The fluidizing liquid may be provided by the feed or by recycling liquid from upper parts of the cell such as from the disengagement zone. Bubbles are introduced into the lower part of the cell through a mechanical impeller which also breaks up any channels in the mixing zone, or by separate aeration in the bottom of the cell or by introduction through a recycle pipe. | 03-15-2012 |
