Abstract

The present invention relates to the use of branched fatty alcohol-based compounds selected from the group of fatty alcohols with 12-16 carbon atoms having a degree of branching of 1-3, and their alkoxylates with a degree of ethoxylation of up to 3, as secondary collectors for the froth flotation of non-sulfidic ores, in combination with a primary collector selected from the group of amphoteric and anionic surface active compounds.
