Definitions
- frothing agents For dressing ores by froth flotation, it is necessary to use collectors and frothing agents, in addition to regulating reagents.
- terpene alcohols in industrial form, for example pine oil have played an important role as frothing agents.
- Further known frothing agents are the homologues of phenol, particularly fractions of tar acid rich in xylenol, and aliphatic alcohols of medium molecular weight such as amyl alcohol, hexanol and heptanol.
