PROCEDE ET APPAREIL DE SEPARATION PAR FLOTTATION

摘要

The invention relates to a floatation method and apparatus. It relates to an apparatus in which the contacting of a suspension of solid matter with a gas is carried out in a venturi tube 20 by introducing the suspension via the mixer head (convergent element) 22 and induction of the gas via orifices formed in the neck 26 of the venturi tube. The mixture obtained is transmitted to a vessel 32 in which the turbulence is low and which ensures rapid separation of the foam. Application to the enrichment (concentration) of minerals using floatation.
