Products application

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.

Storage & Handling

Storage: Store solid xanthates in original properly sealed containers under cool dry conditions away from sources of ignition.

Handling: Wear protective equipment. Keep away from sources of ignition. Use non sparking tools. Equipment should be earthed to avoid static discharge. All electronic equipment should be adjusted for work in explosive environment.
