MECHANISM OF FROTH DEDUSTING AND PRESCRIPTION OF FROTH AGENTS

Analysed the production of froth, the mechanism of froth dedusting, and the structure and properties of surface active aqents, the authors hold that only adding the surface active agents such as the foating agent, wetting agent, stabilizing agent, soluting agent and so on can dedust effectively. Relationships between the hight of froath, surface tension and the density of solution with surface active agents had been gotton by experiment, which provides the theorical and practical basises for developing the prescription of floating agent.
