Flotation Process Flows

The froth flotation process is more than a century old and was developed over a long period of time 8 It takes advantage of the surface chemistry of fine particlesif one particle’s surface is hydrophobic and another is hydrophilic upon generation of air bubbles the hydrophobic particles tend to attach to the air bubbles and float allowing for a separation between particles in the froth and those in the main body ...

The floatation agent preferably sticks to the sulfide minerals rather than the waste minerals and then air is bubbled through the mixture and the floatation agent traps the fine bubbles which carry the sulfides to the surface of the cell where they are carried over aware and separated From there they are dried to provide a concentrate which then goes on to a smelter
