Experimental Techniques in Flotation | SpringerLink

The last decade has seen a flowering of experimental techniques applied to flotation. Some have been no more than an extension of modern instrumentation for chemical analysis, as applied to specific flotation problems. But there has also been a number of simple yet illuminating experiments devised to shed light on particular flotation problems.

How to Improved Fine Particle & Bubble Flotation

Fine-bubble flotation was conducted in a modified 500-g MS flotation cell. A 6-cm-diam, 2-cm-thick disk was used to replace the flotation impeller. Sebba (1985) showed that at high rotation speed, the spinning disk sheared air in the pulp and formed fine-sized bubbles. The cell was tested at 2,800 r/min, 1,300 r/min, and 7,000 r/min.

Column Flotation Cells - Mineral Processing & Metallurgy

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
