Floatation of ultrafine coal

Froth Flotation (Sulphide & Oxide) , People used to float -05mm coal in flotation cells in 1960s,70s and 80s, but now they have switched to -025mm flotation It is recommended that maximum size particle that you try to float be 03mm The reason is that 05mmx025mm flotation requires more residence time than 025mmx0 flotation...

Froth Flotation Process

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbl...

Froth Flotation Cells

Fine coal can be separated from shale and other waste by the process of froth flotation The coal is made water repellent by the addition of a reagent such as oil, so that when a suspension of coal is agitated with air it sticks to the air bubbles and floats to the surface, collecting as froth...
