  SkimAir flash flotation units - Metso

  Metso SkimAir is a flotation cell designed to be installed in a flash flotation role in the grinding circuit. The cell is typically installed on the hydrocyclone underflow stream to capture any sufficiently liberated, fast floating particles that may have reported here. Due to the higher SG of sulphide and precious metal containing minerals ...

  CFD model of a self-aerating flotation cell - ScienceDirect

  2007125 · Abstract The effect of impeller speed on the air flow in a self-aerated Denver laboratory flotation cell was investigated using computational modelling. Air is induced into the slurry by the impeller's rotating action. The rate of air flow is determined by the suction pressure created by the impeller, the hydrostatic head of the slurry and the …
