Briefing
Potassium/Sodium Ethyl Xanthate is a key flotation collector for sulfide ores, enhancing copper recovery. Fast-acting & cost-effective, it requires proper storage & PPE due to CS₂ release. Potassium(Sodium)Ethyl Xanthate
Detailed
What is Potassium(Sodium)Ethyl Xanthate
Potassium/Sodium Ethyl Xanthate is a chemical reagent primarily used as a collector in the froth flotation process for extracting sulfide minerals (e.g., copper, lead, zinc, and gold ores).
Core Features
1.Chemical Type: Organosulfur compound (alkyl xanthate)
2.Primary Use: Collector for sulfide ore flotation (Cu, Pb, Zn, Au)
3.Physical Form: Pale yellow powder/granules (water-soluble)
4.Key Properties: Selective adsorption on sulfide mineral surfaces, Decomposes when heated (releases toxic CS₂ gas), Stable in alkaline conditions
5.Industrial Advantages:Cost-effective, Strong frothing capability, Widely used in large-scale mining operations

Application
As a collector,the selectivity of sodium ethyl xanthate is the most strong in xanthate line.It is widely used in the preferential flotation of readily floatable minerals or complex
sulfide minerals.It is also used in the flotation of copper,lead oxide ores in conjunction with vulcanizing agents.It is also used as precipitant in hydrometallurgical processes
(eg.the refining of zinc electrolyte)and as sulfidation promoter of rubber.
Applications & Solutions
Mining flotation
Sulfide ore collection, priority flotation (separation of multiple sulfide ores), mixed flotation (recovery of total sulfides)
Rubber industry
Vulcanization accelerator
Wastewater treatment
Heavy metal precipitant

FAQ
What are Potassium/Sodium Ethyl Xanthate particles? What are the main components and characteristics?
Potassium Ethyl Xanthate (PEX, C₃H₅KOS₂) and Sodium Ethyl Xanthate (SEX, C₃H₅NaOS₂) are organosulfur compounds formulated as solid particles (powder or granules),
primarily used as collectors in sulfide mineral flotation.
· Appearance： Pale yellow to orange particles (powder/granules)
· Odor： Pungent (rotten cabbage-like, due to CS₂ potential)
· Stability： Decomposes in acid/heat → Releases toxic CS₂ gas
Is granular Ethyl Xanthate better than powder for flotation use?
Granular ethyl xanthate is generally preferred over powder for industrial flotation due to safer handling (less dust/CS₂ exposure), better moisture resistance, and steadier
dissolution, though powders offer faster initial action. Choose granules for stability in large-scale operations or powder for rapid dosing in dynamic circuits - performance
differences are minimal if properly dissolved.
Is 90% ethyl xanthate better in use and transportation than other contents?
90% ethyl xanthate is generally superior for both industrial use and transportation compared to lower purity products, offering higher active content for more efficient dosing,
better flotation performance consistency, and improved storage stability. While it comes at a slightly higher cost, these advantages typically outweigh the price difference.
The higher purity formulation does require more careful handling during transport due to increased CS₂ gas emission risks when exposed to moisture or heat, necessitating
proper sealed packaging and temperature control. For most mining applications, the operational benefits of 90% purity justify its selection, though lower grade
alternatives (80-85%) may be considered for simpler ore processing where cost is the primary concern.
