They also used 2 3 factorial design experiments for higher rank coal flotation to study the influence of kerosene, MIBC and sodium metasilicate (Naik et al., 2005).
Naik et al.  assessed the effect of three 6, 7, 8 and 9; concentration of collector (diesel oil) (g/t) most important reagents for coal flotation: sodium 500, 700, 1000 and 1200; concentration of frother silicate, collector (kerosene) and frother (MIBC), us- (pine oil) (g/t) 45, 80, 120 and 180; concentration of ing 23 full factorial designs.
May 23, 2017 Flotation is carried out at low solids, usually under 10% dilution. In the U. S. on bituminous coal the trend is toward open type No. 30 “Sub-A” Cells, single overflow, and with supercharging. Flows of dilute pulp up to 1500 GPM are effectively treated with excellent results through a single 4-cell machine.

Feb 01, 2021 Terpenic oil or methyl isobutyl methanol is often used as foaming agents for coal/coke flotation (Harvey et al., 2002). There are many literatures on carbon flotation, but most of the carbon flotation materials are from fly ash (Altun et al., 2009, McCarthy et al., 2013, U urum et al., 2011, Walker and Wheelock, 2006, Zhang and Honaker, 2015 ...

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 (Al(OH)3-PAM, or Al-PAM).

Jul 01, 2021 Coal Rejects are a by-product of the coal washing/beneficiation process, in which after separation of beneficiated washed coal and middling, the rejects are left over as a portion of raw feed coal. These are generated from the coarse circuit of the coal washery process.
May 01, 2012 The air flow shows significant negative effect in the Cerrej n coal, indicating that high air flows generate higher bubble sizes, decreasing the bubbles surface area, decreasing the probability of collection between particles and bubbles, deteriorating the selectivity of the flotation process. Jagua coal presents a positive significance in the sulfur rejection, likewise showing a significant positive quadratic effect for Cerrej n coal …
