000000446 520__ $$aFlotation is a widely used process in mineral pro cessing. It utilizes different reagents including, collectors and frothers. It was proposed by Cho and Laskowski to use th e so-called critical coalescence concentration (CCC) for characterization of flotation frothers. In this paper the CCC values were determined for α -terpineol, which is widely used as a frother in laboratory flotation tests, and for (2-dodecanoyloxyethyl)trimethylammonium bromide (DMM-11) which represents a broad family of reagents known as chemodegr adable cationic surfa ctants. The CCC for α -terpineol was found to be 0.16 mmol/dm 3 while for DMM-1, depending of the procedure of approximation, between 0.06 and 0.14 mmol/dm 3 .
