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
