column flotation spargers

Bubble spargers in column flotation: Adaptation to
2000-1-1 Bubble spargers in column flotation 41 The use of efficient monitoring apparatus yields reproducible values for flow rates and allows an accurate flow rate/graduation calibration (correlation coefficient 0.99). The calculation of gas hold-up, i.e. average bubble diameter, thus depends only on the level difference within the manometric tubes.

SPARGERS AND SPARGING TECHNOLOGY SGS
Spargers are an industry tool designed to deliver gas into a column flotation cell or leach tank to ensure that bubbles are dispersed evenly throughout the flotation cell or leach tank. Typically, a column flotation cell can contain up to 20 spargers in order to help the reaction in the cell while up to 16 spargers can be used for a leach tank.
