Recent developments in beneficiation of fine and ultra

Dec 10, 2020 Yang et al. 2019b applied pretreatment on fine coal using compression and investigated the impact of pore structure on collector adsorption and flotation of low rank coal. With compression pressure of 400Mpa and pretreatment using n-dodecane as collector, 74.44 maximum coal yield was obtained which is 20.46 points higher than that of raw ...

Kinetics of Coal Flotation

The Order of Kinetic Models in Coal Fines Flotation

Feb 01, 2016 The purpose of this article is to investigate the order of kinetic models in coal fines flotation. Six kinetic models with different orders were used for flotation tests using fine coals with different average particle sizes, 375, 188, 100, and 37 m, respectively.
