The liquid-phase mixing within CANMET's Western Research Centre's (WRC) 0.76-m-diam pilot-plant flotation column was characterized using a salt tracer. The process variables studied were frother addition and gas and liquid flow rates. The response of the column to a tracer pulse was monitored at three axial and two radial locations. The results showed that the 2-tph flotation column was well mixed. Discussed are the implications of this observation to column design and scale-up.
