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 (25) in the form of a horizontal sheet of water (27). The sheet (27) is typically formed by impinging a downwardly directed liquid jet (23) issuing from a nozzle (22) onto a horizontal plate or disc (24) where it changes direction and travels radially outwards as an axi-symmetric planar liquid jet or sheet (27). The depth of the disc (24) can be adjusted by a support rod (28). 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.
Procédé et appareil servant à injecter de l~eau de lavage dans une mousse de flottation d~un système de séparation par flottation, consistant à injecter l~eau de lavage dans la mousse (25) sous la forme d~une nappe d~eau horizontale (27). La nappe (27) est généralement formée par projection d~un jet de liquide dirigé vers le bas (23) émanant d~une buse (22) sur une plaque horizontale ou un disque horizontal (24) où il change de direction et se propage radialement vers l~extérieur sous la forme d~un jet ou d~une nappe de liquide plan(e) axi-symétrique (27). La profondeur de la plaque ou du disque (24) peut être réglée au moyen d~une tige de support (28). Dans d~autres modes de réalisation, la nappe horizontale est éjectée par une fente horizontale ou la nappe d~eau de lavage est rectangulaire plutôt qu~axi-symétrique.
