<p>The present invention relates to a flotation reagent and a process for the flotation of sulfidic ores. The process comprises contacting the sulfidic ores with a combination of thionocarbamates and mercaptobenzothiazoles to improve the flotation of sulfidic ores, particularly the flotation of copper ore when the copper ore is associated with molybdenum and/or gold. The flotation reagent comprises a combination of compounds of formula (1) and formula (2) where R<SUP>1 </SUP>and R<SUP>2 </SUP>independently of one another are alkyl groups having 1 to 18 carbon atoms, and R<SUP>3 </SUP>and R<SUP>4 </SUP>independently of one another are hydrogen or C<SUB>1</SUB>-C<SUB>6</SUB>-alkyl, and M is hydrogen or an alkali metal, and (1) and (2) are in a weight ratio of (1):(2) of 95:5 to 75:25.</p> |
