In flotation production process, in order to avoid the deterioration of fine slime to the flotation process and remove the harmful effects of fine slime, we often use the following measures. Adding dispersant to reduce its impact when the fine slime is not too much.Pre-desliming before flotation.
Amsterdam: Elsevier Science B.V., 2001. — 368 p. This book is a result of copious notes employed in teaching short courses on fine coal flotation and utilization in Poland, Canada, Brazil and South Africa, as well as various undergraduate courses taught at the Silesian University of Technology in Poland and at the University of British Columbia in Canada.
Jul 01, 2020· The concomitant clay minerals in coal commonly have adverse effects on the coal flotation. In this work, the regulation of coal flotation by cations (Na + and K +) in the presence of clay was investigated to abate this deterioration.It was observed by SEM-EDS that the clay particles coating on the coal surface in low pH condition, which significantly reduced the hydrophobicity of coal.

fine particles in flotation (Chander and Polat, 1995; Chander et al., 1995). Hence, it is difficult to deter-mine the effect of primary particle size on the rate of flotation of fine coal particles. Interpretation of flotation results for coals where oily collectors are used require knowledge of the emulsification behavior of the oily collector ...

Flotation is commonly used to treat fine coal (typically below 500 microns in size) and is a complex, three-phase process that is controlled by factors which can be divided into three facets: coal, chemistry and machine. It is most often used for treating metallurgical coal fines where the value of the product can justify the added ...
Kinetics is an important aspect of fine coal flotation (Wills and Napier-Munn, 2006; Li et al., 2012). The flotation rate determines the time needed for removal of ash from raw coal. Coal particles with different sizes and densities have different flotation rates. Most flotation rate tests show that the fine coal .
