Effect of slimes on the flotation recovery and kinetics of coal particles
In contrast, slimes decreased the flotation recovery of coal particles at a high mass proportion of slime particles. Furthermore, for the coal particles in 0.5–0.25 mm size range, slimes increased its flotation rate at a low mass proportion of slime particles, otherwise slimes decreased its flotation rate.
Iron ore slimes flotation
Flotation was impaired by slimes coating caused by kaolinite particles. Trahar (1981) investigated the relationship between particle size and collection efficiency in flotation. In summary, the collision efficiency is a function of particle size and the adhesion efficiency is related to both, the mineral hydrophobicity degree, and particle size ...
Modeling and Optimisation of Spiral Concentrator for …
The iron ore slime is discarded due to its particle size and chemical composition which are not suitable as feed to the blast furnace. Although the fines/slimes can be agglomerated to larger particle, the alumina to silica ratio which is normally more than one poses serious problem during sintering process and subsequent smelting in blast ...
Flotation kinetics performance of different coal size fractions …
The flotation kinetics of different size fractions of conventional and nanobubble (NB) flotation were compared to investigate the effect of NBs on the flotation performance of various coal particle sizes. Six flotation kinetics models were selected to fit the flotation data, and NBs were observed on a hydrophobic surface under hydrodynamic cavitation by atomic force …
