Process for the selective flotation of metal ores using 2-mercaptothi-azole derivatives

A process for the selective flotation of metal ores is described, wherein ionic organic collectors are utilized, which have the formula: (I) where R and R1, like or different from each other, represent: H, a halogen, a straight or branched C1-9 alkyl group, an alkoxyl or hydroxyalkyl group in which...

Zusammenfassung:A process for the selective flotation of metal ores is described, wherein ionic organic collectors are utilized, which have the formula: (I) where R and R1, like or different from each other, represent: H, a halogen, a straight or branched C1-9 alkyl group, an alkoxyl or hydroxyalkyl group in which the alkyl moiety contains from 1 to 9 carbon atoms, or a phenyl group; and M represents: H, Na, K, Li, Cs, NH4.
