Product Detail

Product Tags


Potassium ethyl xanthate (PEX) is best for the recovery of sulfides that are relatively hydrophobic like galena. It is recommended for lead-zinc ores, low grade copper ores, and ores that contain a minimal amount of zinc, but it is not recommend for partially oxidized ores because it will not have the pulling strength to recover wanted minerals. Collector PEX will be more selective against iron sulfides than other xanthates at low PH.
Feeding method: 10-20% solution
Usual dosage: 10-100g/ton
