Flotation Frothers
For effective flotation to take place there were two problems that had to be corrected. The air bubble had to be strong enough to support the weight of the mineral on its surface, and it was also required to be able to withstand the internal pressure caused by the air expanding as it came to the surface of the slurry.

The Importance of pH in Flotation
This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit. An alkaline solution is also slightly caustic, this will help clean the surface of the mineral. This strengthens the bond between the collector and the surface of each mineral particle.
