Mar 15, 2017 · An experimental investigation was carried out to improve the froth flotation method of separating coal pyrite. The effect of several surface active agents on the floatability of an Iowa coal and its associated pyrite was studied in both the presence and absence of methyl isobutyl carbinol (MIBC), a commonly used frother.

Oct 09, 2007 · In a previous study, various pyrite depressants were examined to improve the flotation performance of a coppersulfide ore containing tetrahedrite (Cu12Sb4S13). Optimal results from this study were used to examine the effect of elevation on recovery and grade. Tests were conducted at elevations of 3,350 meters, 1,735 meters, 610 meters, and760 meters, consisting of five repetitive .

Effect of four frothers,including MIBC,BK201,terpenic oil and 2Ethylhexanol,on the flotation behavior of quartz and pyrite was investigated and ore flotation tests were carried of single mineral tests show that,quartz is floated into concentrates through froth entrainment,while pyrite is also pulled into flotation concentrates under the dual action of hydrophobic floating and ...

A more negative value of interaction parameter (â)and heat of adsorption are found at 90:10 ratio of frother blend. Flotation studies of coal fines were studied with above two types of frothers and their blend. It is found that recovery of carbon value increases significantly when a 10% (w/w) of powerful frother was added with MIBC.

An identifiion of the characteristics of microbbubles dispersion is presented in this paper, when frother addition (MIBC) is modified in a biphasic system (airwater). Sauter diameter (d32), gas flow rate (Jg), superficial area flow density of the microbubbles (Sb) and air holdup (εg) are the measured variables in this research work. The studied frother additions were 0, 10 and 20 ppm.

The experiments described herein indie that the frothers control the size of bubbles in flotation systems by controlling bubble coalescence. The ability of frothers to prevent bubble coalescence is well characterized by the Critical Coalescence Concentration (CCC). At frother concentrations C lower than CCC, the bubble size is determined by coalescence. At frother concentrations that exceed ...
