ABSTRACT:
In a method for enriching oxidized ores by froth flotation, use is made, as collector, of a combination comprising : at least a first compound selected among amino-l-alkane products having the general formula R.sub.1 - (NH CH.sub.2 CH.sub.2 CH.sub.2)n NH.sub.2, wherein R.sub.1 is a saturated or unsaturated straight- or branched-chain hydrocarbon group containing from 8 to 18 carbon atoms, and n is an integer ranging from 0 to 3, and at least a second compound selected among amino-ether products having one amino function and at least one ether function, of the general formula R.sub.2 - O - (CH.sub.2 CH.sub.2 O)n - CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2, wherein R.sub.2 is a saturated or unsaturated straight- or branched- chain hydrocarbon group containing from 2 to 18 carbon atoms, and n is an integer ranging from 0 to 2.
