ARYL MONOSULFONATE COLLECTORS USEFUL IN THE FLOATATION OF MINERALS

摘要

2098574 9211091 PCTABS00014 Dialkylated aryl monosulfonic acids or salts thereof or their mixture are useful as collectors in the flotation of minerals, particularly oxide minerals. Collector compositions comprising these salts and oleic acid are particularly useful in hard water. Collector compositions comprising these salts and sulfide collectors such as xanthates are useful in flotations conducted at natural pH of the slurry.
