ABSTRACT:
Dialkylated aryl monosulfonic acids or salts thereof or their mixture are useful as collectors in the flotation of minerals, particularly oxide minerals. Particularly useful are those sulfonic acids or salts in which the alkyl substituents are unsymmetrical. Collector compositions comprising these salts and sulfide collectors such as xanthates are useful in flotations conducted at natural pH of the slurry.
