The effect of particle size on the flotation behavior of coal fly ash was investigated in this study. Three narrow particle size fractions, 125 + 74 μm, 74 + 45 μm, and 45 μm, and the unclassified particle size fraction of 500 μm of coal fly ash were chosen to study the basic properties by the measurement of induction time, contact angle, and wetting heat.

flotation of slime in Ertang Coal Preparation Plant. Firstly, industrial analysis and sieving test of the floating slime were carried out. The results show that the flotation efficiency is the best when the collector dosage is 400g / t and the amount of ing agent is 600g / t, that is, the ratio of collector to ing agent is 2: 3.

Pyrite is removed from coal by means of a twostage froth flotation process. In the first stage, coarse pyrite is removed as underflow in a conventional froth flotation operation. In the second stage, the froth product from the first stage is subjected to froth flotation using a coal flotation depressant and a pyrite flotation collector, thereby removing a substantial proportion of fine pyrite.
