Further Investigations on Simultaneous Ultrasonic Coal

2017922&ensp·&enspFlotation was carried out with a newly designed flotation cell refurbished from an old ultrasonic cleaning bath (2.5 L volume) equipped with a single frequency (35 kHz) and two different power levels (80–160 W) and a subaerationtype flotation machine operating at a stable impeller speed (1200 rpm) and air rate (2.5 L/min).

Effects of operating parameters on timedependent ash

20191122&ensp·&enspflotation machine with a 2l cell volume. For each semibatch test, a requisite amount of bulk coal sample was transferred into the cell and additional tap water (pH 7۪.2) was added to maintain the required pulp density. The impeller speed of the flotation chamber was set, and the pulp was allowed to condition for 5 min.

Further Investigations on Simultaneous Ultrasonic Coal

2017922&ensp·&enspThe coal flotation reagent was chosen as Ekofol440 (Ekof, Bochum, Germany), which is a commercially used oily collector and frother mixture consisting of aliphatic alcohols in the C6 to C10 range, as well as phenols and phenol derivatives. Coal flotation experiments were conducted by use of a redesigned flotation cell refurbished
