ABSTRACT
This study investigated the effect of temperature (15; 25; 35°C) on the kinetics and flotation efficien-cy of hard (ortho-coking) coal using a fixed dose of machine oil as a collector and α-terpineol as a frother. The results show that coal flotation occurs fastest and most efficiently at 15°C, achieving a volatile fraction recovery of 77%. At 35°C, the recovery of vola-tile parts was 66%, or 47% at 25°C. At the same time, hard coal flotation at 15°C was found to reach a recovery of 45% after just five minutes, almost four times faster than flotation at 25°C.
