| Abstract: | The effects of ultrasonic frequency, power and treatment time on the scarce difficuh-to-float fine coals were studied. The experimental results of ultrasonic and ordinary flotation were compared. When the ash content of the clean coal of ultrasonic flotation was lower than that of ordinary flotation by 1.26% , the clean coal yield and the perfect index flotation were increased by 17.34% and 13.15% respectively. The study shows that ultrasonic treatment could enhance the performance of flotation for the scarce difficult-to-float fine coals. |
