Speciality Collectors Xanthogen formates Particularly useful as flotation reagents, specifically collectors in the flotation of molybdenum-bearing copper ores, where molybdenum recovery has been increased by more than 10% without adverse effects on copper recovery. · Can be used as a collector in most base and precious metal flotation circuits. · Improved recovery of copper in acid circuits · Excellent as secondary collector in porphyry copper operations · Ideal as blend component in frothers
Xanthic esters Synonym: (xanthogenic acid) · Excellent collector for metallic copper, molybdenite, and sulfidized base metal oxides. · Effective in both acid and alkaline solutions. · Insoluble in water (oily compound) · May be combined with thiocarbamates and other specialty collectors
Also available are specialized blends with mercaptans as excellent collectors in copper/moly flotation circuits. |
