Sammendrag
It is well known that mixtures of various collectors or collectors and frothers show
often a synergetic effect [1-7], i.e. their overall effectiveness is greater than expected
from their individual characteristics. This synergetic effect can affect significantly
recovery and selectivity of a separation proces, and can also be related to
foamability and foam stability. The paper presents a systematic investigation on the
influence of mixtures of three cationic alkyltrimethylammonium bromides (CnTAB,
n=8, 12, 16) and non-ionic n-octanol (C8) surfactants on foamability and flotation of
quartz.
