Flotation Frothers Frothing Agents

As a given volume of air becomes associated with larger bubbles, the probability of a collision of bubbles with particles is dramatically decreased thus diminishing the effectiveness of the separation process. To handle this coalescence, a broad family of nonionic surfactants, denoted as frothers in the flotation literature, is used.
