a. The act, process, or condition of floating. Also called flotage.
b. The act or an instance of launching or initiating, especially the floating of stocks or bonds.
c. The capability, especially of a vehicle tread or tire, to remain on top of a soft surface, such as sand, wet ground, or snow.
2. The process of separating different materials, especially minerals, by agitating a pulverized mixture of the materials with water, oil, and chemicals. Differential wetting of the suspended particles causes unwetted particles to be carried by air bubbles to the surface for collection.

(fləʊˈteɪʃən) or

floatation

n
1. (Stock Exchange)
a. the launching or financing of a commercial enterprise by bond or share issues
b. the raising of a loan or new capital by bond or share issues
2. (Nautical Terms) power or ability to float; buoyancy
3. (Metallurgy) Also called: froth flotation 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
