Novel control for froth flotation cells

The performance of the froth is controlled by the airflow used to create it. Air recovery, is a measure of the volume of air or other gas retained in the froth as it overflows from the flotation cell compared with the volume of air/gas used to create the froth initially. In other words it is a measure of the stability and effectiveness of the ...
