Gas dispersion measurements in a flotation cell

Abstract. Three new techniques for measuring gas dispersion properties: local gas holdup, local gas rate (superficial gas velocity) and bubble size distributions have been developed. Gas dispersion properties were measured in a 50 L lab scale flotation cell, using these techniques. The cell was operated under batch conditions, two-phase …

What Are Column Flotation Cells?

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

A Review of Flotation Physical Froth Flow Modifiers

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …

The future of flotation

Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes. First, coarser particles tend not to have as ...
