Column Flotation Eriez Flotation Division
Basic Idea Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter-current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice and allows the user to optimize the performance based on the feed characteristics
Chat OnlineOverview of flotation as a wastewater treatment technique
In mineral flotation it is necessary to produce a stable froth at the free surface of the flotation cell. In applications to wastewater treatment an stable foam is not required. • In mineral flotation the overall process is economically attractive. In environmental application usually flotation means an extra cost.

Chat OnlineIntroduction to Mineral ProcessingChevron Phillips Chemical
The ability of a mineral to float depends upon its surface properties. Chemical modification of these properties enables the mineral particles to attach to an air bubble in the flotation cell. The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell.
