Effect Of Ultrasonic Pretreatment On Oxidized Coal Flotation

Effect Of Ultrasonic Pretreatment On Oxidized Coal Flotation

In this work the effect of ultrasonic pretreatment time on oxidized coal flotation was studied. Analytical techniques such as particle size distribution PSD scanning electron microscopy SEM X-ray photoelectron spectroscopy XPS contact angle measurement and specific surface areapore analysis were used to examine the changes in the physicochemical characteristics of the coal .

Effect Of Oxygen Functional Groups On The Surface

Effect Of Oxygen Functional Groups On The Surface

ABSTRACT The surface properties and flotation response of coal samples of different rank correspond to results from similar experiments for coal samples with different degrees of oxidation. Three principal types of oxygen-containing functional groups C O C-O O C-O were detected at the surface of low rank coals and oxidized coals by XPS complementing results of previous researchers .

Ash Depression In Fine Coal Flotation Using A Novel

Ash Depression In Fine Coal Flotation Using A Novel

The current study investigated the effects of novel hybrid polyacrylamide polymers as ash slime depressants in fine coal flotation to enhance combustible recovery and ash rejection. Coal samples at P80 of approximately 45 um with ~25 ash content were floated in the presence of in-house synthesized hybrid aluminum hydroxide polyacrylamide polymers AlOH3-PAM or Al-PAM.

Chemical Conditioning Of Fine Coal For Improved Flotation

Chemical Conditioning Of Fine Coal For Improved Flotation

A major advantage of potassium monopersulfate for fine coal flotation is the improved ash rejection which develops during the flotation. This is apparent from FIGS. 5 6 7 and 8. FIG. 5 illustrates a single-stage flotation process where ash content is measured with respect to yield for high-volatile bituminous coal at different pH values.
