DEFINITION

Classification: 210/703

Effecting flotation:

(under subclass 702) Process in which a dissolved or dispersed constituent in the liquid is caused to rise toward an upper surface by use of an agent which reduces the apparent density of such constituent.

(1) Note. The agent may cause gas bubble which attach themselves to particles or it may be a light liquid which wets and associates with the constituent, causing it to float.
