Column Flotation Cells
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.
Sanding in flotation cells
First off let us discuss why and how sanding occurs, because that does have an impact. Sanding can occur for many reasons, the two main and most common being; 1) poor classification ahead of flotation allowing oversized material to enter the cells, and 2) impeller wear leading to poor mixing in the cell.

Flash flotation is a process designed to remove coarse, liberated, fast floating minerals from hydrocyclone underflow. Irrespective of liberation, coarse particles would normally remain in a grinding circuit until they are reground fine enough to report to the hydrocyclone overflow. Additionally, minerals of high density also report to hydrocyclone underflow …
