Summary:2-mercapto-benzoxazole derivatives, having formula (I): wherein: R, R1, R2 and R3, being the same or different, are each H, or a straight or branched alkyl, alkoxyl or hydroxalkyl group with up to 12 carbon atoms; and M is H, Na, R, Li, Cs or NH4; are employed as collectors for the selective flotation of sulphide ores to separate mineral salts containing copper, zinc and silver.
