Sparging

Column Flotation requires a Sparging System

Sparging is the controlled generation of an ultra-fine swarm gas bubbles, specifically into a flotation column promoting the attachment of hydrophobic particles and generally into other vessels for leaching or hydrometallurgical applications.  The EFD advantage is the ability to provide two types of sparging systems: SlamJet™ insertion spargers for general purpose flotation and leaching and CavTube hydrodynamic spargers capable of generating much finer bubbles for the recovery of fine particle size fractions.

 

Eriez Flotation Division offers a few Sparging options

EFD’s patented SlamJet™

air sparging system comprises an air manifold that surrounds the column cell and supplies air to a series of SlamJet™ sparger tubes. The top of the manifold is fitted with connections for air, as well as connections for a pressure gauge and a pressure transmitter. The side of the manifold is equipped with a series of couplings for connecting to the sparger tubes and is also fitted with one or more drains located at the bottom of the manifold.

 

Cavitation Tube Sparging

generates “pico-bubbles” substantially increasing the surface area available to the desired target particles. Cavitation Tube Sparger is at the heart of aeration systems used for bubble generation in column flotation cells. The “Cav-Tube” is a hydro-dynamic sparger shaped to maximize fine bubble generation effectively increasing the superficial surface area rate (Sb) of air moving through a column flotation cell.
