Concentrate flow rates were measured for the flotation of −100mesh Lower Kittaning coal in a computercontrolled 0076 x 35m pilot flotation column The variables studied were recovery zone height airflow and solid feed rates The specific projected surface areas of the feed concentrate and tailing streams were determined from the measured particle size distributions

Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated andor aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic waterrepellent by conditioning with selective flotation reagents However in column flotation there is no
