THE COLUMN FLOTATION ADVANTAGE Flotation columns work on the same basic principle as mechanical flotation equipment – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective reagents.
The DEC Flotation column has two cells, each 2.5 m deep stacked one above the other with the top cell operating as a rougher and the lower cell, which is fed from the top cell, acting as a scavenger cell.

There are several features of flotation columns which promote greater separation efficiency.Some of these features include: • Cell geometry • Froth washing • Highly controllable air sparging system Cell Geometry The geometry of flotation column offers some advantages over convention cells.
“One key trend is to use a mix of mechanical cells and flotation columns with columns as the final cleaner stage, because they deliver increased recovery and higher grades in this role,” he said.Over the past few years, we’ve seen mechanical cells used for rougher and scavenger duties, and generally the first cleaner stage as well.
“Sum the range of values from the cell 12 columns to the left (C[–12]) in the same row through the cell that is one column to the left (C[–1]) in the same row.” Because in all the cells where we are calculating the total, the range of values is in the same order and that’s why we have the same formula for all the cell.
“The efficiency of this flotation device surpasses that which can be achieved by other individual techniques or separators.
