US20090008301A1 - Methods of Increasing Flotation Rate ...
Methods of increasing the rate of separating hydrophobic and hydrophilic particles by flotation have been developed. They are based on using appropriate reagents to enhance the hydrophobicity of the particles to be floated, so that they can be more readily collected by the air bubbles used in flotation. The hydrophobicity-enhancing reagents include low HLB surfactants, naturally occurring ...

Flotation Frothers - Frothing Agents
Flotation Frothers – Frothing Agents. The next reagent that is added is the Flotation FROTHER. The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which attaches itself to the air.

Flotation O idised Copper Ore
Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation. The minerals that do not float into the froth are called the flotation tailings or flotation tails. The froth flotation process was first patented by H. F. K. Pickard, E. L.Sulman and John Ballot in the year 1906.
