Column and Contact Cell Flotation Mining SGS

As with a flotation column, the froth may be water washed meaning the contact cell can also be used as a cleaner cell. The contact cell is mainly used in rougher flotation circuits. It is compact, highly efficient, simple to operate, and has low energy and maintenance costs.

What Are Column Flotation Cells? Industrial Resources

Feb 06, 2019· 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.

FLOTATION Froth Processes and the Design of Column Flotation Cells. I.M. Flint, M.A. Burstein, in Encyclopedia of Separation Science, 2000. Pre-Aeration. Columns, by nature, have low turbulent momentum between the bubbles and particles, meaning that smaller particles have slow flotation kinetics in these vessels. The column is, however, a

Flotation Process an overview ScienceDirect Topics

The most common examples of pneumatic cells are the column cell and the Jameson cell. As shown in Fig. 5.36, a flotation column is typically a tall vertical cylinder. It is fed with coal pulp at the top third of column. It has no mobile parts or agitators. Air bubbles are injected either through external or internal spargers at the bottom.
