column and contact cell flotation mining sgshowever, in column flotation, there is no mechanical mechanism causing agitation. as well, separation takes place in a vessel (known as a column) that is much taller than the width (or crosssection) of the cell. air is introduced into the slurry in the column through spargers, which create a countercurrent flow of air bubbles.
