Floatation | Article about floatation by The Free Dictionary
flotation, floatation 1. power or ability to float; buoyancy 2. a process to concentrate the valuable ore in low-grade ores. The ore is ground to a powder, mixed with water containing surface-active chemicals, and vigorously aerated. The bubbles formed trap the required ore fragments and carry them to the surface froth, which is then skimmed off Collins ...
