Physical and chemical interactions in coal flotation

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 emulsifi ion behavior of the oily collector

Regulation of coal flotation by the ions in the presence

The concomitant clay minerals in coal commonly have adverse effects on the coal flotation. In this work the regulation of coal flotation by ions 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
