Simply said a Flotation Collectors is a chemical used to make the surface of minerals which is metallic hydrophobic or in layman’s term ‘afraid of water’ or ‘water hating’ as others like to say This chemical used will behaved in a way as a wax would when you applied it to your car After wax or hydrophobic agent is adhered to the surface that surface with see water pearl

What happens when there is too much flotation collector how do you know and how can to estimate The bubble will react as if there is too little depressant Froth bubbles will get smaller and closer together but the unlike the depressant it won’t cause the mineral to fall off of the bubble due to overloading Remember there is enough depressant to keep the majority of unwanted mineral from

different variables such as collector concentration conditioning time air flow rate AFR and air bubble size on flotation recovery of galena were also investigated in the presence of each xanthate with different chain lengths and structures 2 RESULTS AND DISCUSSION 21 Effect of Collector Concentration on Flotation Recovery
Apr 25 2014 · Froth flotation is a widely used process of particle separation exploiting differences in surface properties It is important to point out that overall flotation performance grade and recovery is a consequence of the quality and quantity of the solid particles collected from the pulp phase transported into the froth phase and surviving as bubbleparticle aggregates into the overflow
