Abstract

Concentrate flow rates were measured for the flotation of -100-mesh Lower Kittaning coal in a computer-controlled 0.076 × 3.5-m 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. The results obtained show that the concentrate flow rate was independent of recovery zone height but was dependent on the hydrostatic pressure setting (measure of froth depth), gas flow rate, solid loading and particle size. New correlations for column carrying capacity and yield are provided as a function of bubble surface area flux and the specific particle projected surface area.
