:: CPT CavTube spargers... Smaller Bubbles... Higher Recoveries

Eriez Flotation Group has applied external hydro-dynamic sparging systems, i.e. CavTube spargers for a variety of industrial column flotation applications ranging from iron ore, phosphate, fluorite, niobium, feldspar and mica to molybdenum.


CavTube spargers generate very fine bubbles through hydro-dynamic cavitation. The CavTube generated ‘pico-bubbles’ have been shown to demonstrate substantial improvements to column flotation kinetics with benefits including:

  • Higher target particle attachment probability
  • Higher flotation recoveries
  • Reduced flotation reagents
  • Longer sparger operating life
