Abstract
The invention relates to a composition which is effective as a flotation reagent for collecting and separating potash salt mixtures. The flotation reagent comprises A) at least one compound of the formula [R1—NH3]+X−, where R1 is a C8 to C22 alkyl radical and X− is an anion, and B) a branched fatty acid having a chain length of 8 to 22 carbon atoms.
