Best Air Sparging System for Column Flotation

Objective: Provide a lowmaintenance, reliable means of generating bubbles and controlling bubble size for column flotation Approach: Commercial sparger systems used in flotation columns to process minerals provide only limited means of controlling the size of bubbles generated and the rate of air To achieve separation, an air sparging device is required to produce bubbles in the flotation cell In column flotation operations sparging devices generate small bubbles into the cell to carry the desired mineral to the surface for later recovery and processing However, field studies suggest that air injector systems are not always optimizedOPTIMIZATION OF AIRINJECTION SPARGERS FOR COLUMN FLOTATION ABSTRACT of mineral systems with high kinetics, very small gas bubbles will tend to hurt froth mobility, and hence are undesirable generation is jet sparging of air through orifices Air is forced under high pressure (30100 psig) through annularColumn Flotation SGSIM Flint, MA Burstein, in Encyclopedia of Separation Science, 2000 History The first pneumatic flotation cell, which used air sparging through a porous bottom and horizontal slurry flow, was patented in 1914 by Callow The first countercurrent column flotation device Air Sparging an overview ScienceDirect Topics Development of a Novel Air Sparging Device Andrew Reid Hobert ABSTRACT Column flotation is commonly employed in the processing and recovery of fine mineral particles due to an increase in flotation selectivity unattainable using conventional flotation methods Such an increase in selectivity is due to the employment of wash water, minimizingDevelopment of a Novel Air Sparging Device

Sparging technology has evolved significantly over the past three decades, progressing from simple pipe systems to systems that include automatic slurry backflow protection In this article we examine the different types of sparger technologies available and the most important factors to consider when choosing the most suitable air sparging bubbles, which are injected at the bottom of the column This air can be generated by internal or external sparging systems It is common to separate the flotation column in two distinctive zones: the froth zone and the collection zone In the collection zone, hydrophobic materials are collected by the air bubbles and transferred to the froth zoneFlotation Column: A Process Unit for Cleaning Up Paper • Aeration of Column Flotation Cells • PreAeration Systems An acrylic model of an Eriez CavitationTube sparging systems have been demonstrated on an industrial scale in coal, base metals, sulﬁdes and CavTubes can also be used to replace older style airlance systems to gain additional recovery in ultraﬁne applicationsCAVITATION TUBE SPARGING SYSTEMS Eriez Flotation Figure 9 Laboratory comparison of three column sparging systems (Kohmuench, Precombustion of Hazardous Air Pollutant Precursors, PhD Dissertation, Virginia Tech, 1998) 25 Figure 10 Effect of Sb on flotation recovery for two different air spargingREDESIGN OF INDUSTRIAL COLUMN FLOTATION Minerals Engineering, Vol 4, Nos 711, pp 911923, 1991 08926875/91 $300+000 Printed in Great Britain Pergamon Press plc COLUMN FLOTATION: A SELECTED REVIEW, PART II GS DOBBYand JA FINCHt Dept of Metallurgy and Materials Science, University of Toronto, Toronto, Canada M5S I A4 f Dept of Mining and Metallurgical Engineering, McGill University, Montreal, Column flotation: A selected review, part II
