Abstract
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.
