Product Description
Dithiophosphate 25 (Dicresyl Dithiophosphate Acid) is a dark brown oily liquid, widely recognized for its dual capturing and foaming properties. This versatile flotation collector is highly effective for sulfide ores of lead, copper, and silver, as well as activated zinc sulfide ores. Its ability to work in both neutral and acidic media makes it a reliable choice for mineral beneficiation processes, particularly in lead and zinc preferential flotation operations.
Key Features and Benefits
Dual Functionality:
- Combines capturing and foaming properties for enhanced flotation efficiency.
- Strong collector for sulfide ores of lead, copper, silver, and activated zinc.
Selective Performance:
- Exhibits weak collection ability for pyrite and other sulfide minerals in alkaline circuits, reducing unwanted mineral recovery.
- Functions as a strong non-selective collector in neutral or acidic media.
Wide Applicability:
- Effective in lead-zinc preferential flotation separation.
- Offers certain collection effects for heavy metal oxide ores under specific conditions.
Ease of Use:
- Slightly soluble in water; can be directly added to the adjustment tank or ball mill in its original form.

Packaging and Storage
Packaging:
- Plastic Drums: 200 kg per drum, 4 drums on a wooden pallet, 80 drums per 20' FCL (16 MT).
- IBC Tanks: 1000 kg per IBC, 20 IBCs per 20' FCL (20 MT).
Storage:
- Store in a dry, well-ventilated place, away from heat and sunlight.
- Follow "first in, first out" storage principles to maintain quality.
- Avoid freezing; store in plastic or coated steel drums.
Safety and Handling
Precautions:
- Avoid direct contact with skin and eyes; use safety glasses, natural rubber gloves, and protective clothing.
- Ensure proper ventilation to avoid inhalation of vapors.
Special Handling:
- Use non-sparking tools to prevent static discharge.
- Follow MSDS guidelines for safe operation.
Environmental Impact
Eco-Friendly Design:
- The majority of the reagent binds with the concentrate and decomposes during subsequent processing.
- Minimal residue transferred to tailings; avoid release into water systems to reduce environmental risks.
