View source for Air bell

In froth flotation, the small air pocket inducted or forced into the pulp at depth; e.g., bell and the two-walled semistable bubble after emergence from pulp into froth have different characteristics and gas-to-liquid, area-to-volume relationships, hence the distinction. These bubbles vary in attractive and retaining power for aerophilic grains and are a critical component of the flotation process.
