Briefing
Dithiophosphate 25 is a high-performance flotation collector for gold & copper sulfide ores, enhancing mineral recovery. Cost-effective & selective, it also acts as a depressant for pyrite.
Detailed
What is Dithiophosphate 25
Dithiophosphate 25 (DTP 25) is an advanced organophosphorus flotation collector widely used in mineral processing.
Core Features
1.Function: Selective collector for sulfide ores (Cu, Pb, Zn, Au, Ni).
2.Advantages:
（1）High pyrite rejection (reduces unwanted iron sulfide).
（2）Stable in acidic to neutral pH (pH 3–9).
3.Form: Liquid or water-soluble powder (industrial mixtures).

FAQ
What are dithiophosphate 25 particles? What are the main components and characteristics?
Dithiophosphate 25 (DTP 25) is an organophosphorus flotation collector available as powder/granules or liquid, primarily composed of alkyl dithiophosphate salts. It exhibits high selectivity for
copper/lead/zinc sulfides over pyrite, functions effectively in acidic to neutral conditions (pH 3-9), and offers advantages like enhanced metal recovery and cost efficiency. The yellowish-brown
particles are water-soluble but require cool, dry storage to prevent H₂S release. Its composition varies by supplier, so SDS verification is recommended for precise specifications.
What advantages does Dithiophosphate 25 have over Xanthate?
Stronger selectivity: Its inhibitory effect on pyrite is superior to that of xanthate.
Good acid resistance: It remains effective in low pH (3-9) environments and is suitable for acidic pulp.
Flexible compounding: It is often used in combination with yellow medicine to reduce the overall cost of medication.
How should Dithiophosphate 25 be stored? What are the security risks?
Storage: Keep in a cool and dry place, sealed and moisture-proof (avoid decomposition to produce H₂S).
Risk: Contact with acids or high temperatures may release toxic gases (H₂S/CS₂). Protective equipment (gloves, masks) is required.
