Application
- Potassium ethyl xanthate, as the mining reagent, is the weakest xanthate , but PEX is very selective given the correct chemical conditions.
- It is best for the recovery of sulfides that are relatively hydrophobic like galena.
- Potassium ethyl xanthate (PEX) can recover all sulfides but because of its weak nature, the flotation kinetics are very slow.
- Flotation Collector PEX(Potassium ethyl xanthate) is not recommended for copper sulfide or copper-activated sphalerite flotation unless the head grades are low.
- This is due to the large retention required to compensate for the slow kinetics. It is also not recommend for partially oxidized ores because it will not have the pulling strength to recover wanted minerals.
- Mineral processing flotation Collector-Florrea PEX is recommended for lead-zinc ores, low grade copper ores, and ores that contain a minimal amount of zinc.
- Collector PEX will be selective against iron sulfides at lower pHs than other xanthates.
