Potassium Ethyl Xanthate Supplier Malaysia
- Also known as
- PEX
- KEX
- Potassium Ethyl Dithiocarbonate
Potassium ethyl xanthate is a sulphide-mineral flotation collector for Malaysian mining and mineral-processing enquiries. It is also known as PEX, KEX or potassium ethyl dithiocarbonate and must be distinguished from sodium ethyl, isopropyl, isobutyl and amyl xanthates.
Commercial requirements may specify powder, granular or lower-dust forms together with active content, moisture and free-alkali limits. Particle form matters where plants use manual charging, enclosed preparation systems or automated dosing equipment.
PEX is selected within a complete flotation scheme according to ore mineralogy, pH, collector strength and selectivity targets. It should not be substituted for another xanthate member without metallurgical testing and process approval.
Send the required potassium ethyl xanthate form, activity specification, quantity, application and delivery location with your enquiry. Availability, packing and documentation are confirmed with the quotation.

Potassium Ethyl Xanthate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Standard flotation grade PEX | pale yellow powder or granules | — | Sulphide-mineral flotation circuits requiring a shorter-chain potassium xanthate collector. | Confirm the required sealed pack format with the quotation. |
| Granular or low-dust PEX | free-flowing granules | — | Mineral-processing plants seeking easier charging and reduced dust during reagent preparation. | Confirm the required sealed pack format with the quotation. |
| Specification-controlled PEX | powder or granules | — | Qualified flotation programmes that define active content, moisture, free alkali and particle-form limits. | Confirm the required sealed pack format with the quotation. |

Common questions about potassium ethyl xanthate
What do PEX and KEX mean?
Both abbreviations are used for potassium ethyl xanthate, also called potassium ethyl dithiocarbonate in chemical identity references.
How is potassium ethyl xanthate different from PAX?
PEX has an ethyl group while potassium amyl xanthate has a longer amyl group, giving different collecting strength and selectivity.
Which minerals can potassium ethyl xanthate collect?
It is used in selected sulphide-mineral flotation systems, but suitability and dosage depend on ore mineralogy, pH and the full reagent scheme.
What specifications should be included in a PEX enquiry?
State active content, moisture, free alkali, particle form, preferred handling format, monthly quantity and the incumbent flotation specification.
Can a lower-dust granular PEX form be requested?
Yes. Include the plant charging method and preferred particle form so suitable granular or compacted options can be assessed.
