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.
power or ability to float; buoyancy
3. 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
