Introduction
Flotation is the backbone of modern mineral processing, and selecting the right collector plays a decisive role in achieving higher recovery rates and better concentrate quality. Dithiophosphate 25, a dark brown oily liquid, has established itself as an advanced flotation reagent for lead, copper, and silver sulfide ores, as well as for activated zinc sulfides and selective heavy metal oxides. Its unique balance of collecting and foaming properties makes it indispensable for improving efficiency in complex flotation circuits.
In this article, we dive into how Dithiophosphate 25 enhances the flotation process, its key advantages, and why it is trusted by mineral processors worldwide.

6. Cost-Effective Solution
- Its efficiency at relatively low dosages makes it an economical choice for large-scale operations.
4. Application Guidelines
To optimize the use of Dithiophosphate 25, follow these best practices:
-
Dosage Recommendation
- Typical dosage ranges between 5-100 g/ton of raw ore. Fine-tune based on flotation tests and ore characteristics.
-
Point of Addition
- Add Dithiophosphate 25 directly to the adjustment tank, ball mill, or flotation circuit in its original liquid form to ensure uniform dispersion.
-
Circuit Conditions
- Best results are observed in neutral or acidic media, though its weak pyrite collection in alkaline circuits allows for selective separation.
-
Compatibility
- Test the compatibility of Dithiophosphate 25 with other flotation reagents (e.g., frothers and depressants) to achieve optimal process synergy.
5. Safety, Handling, and Storage
Safety Precautions
- Always wear protective equipment (safety glasses, gloves, and rubber aprons) to avoid skin and eye contact.
- Operate in well-ventilated areas to prevent inhalation of vapors.
- Use grounded equipment to avoid static discharge during handling.
Storage Guidelines
- Store in a dry and well-ventilated area, away from heat sources, sunlight, and freezing conditions.
- Keep in sealed plastic drums or coated steel containers for product longevity.
- Follow the "first in, first out" principle to maintain inventory quality.
Packaging
- Plastic Drums: 200 kg per drum (16 MT per 20-foot container)
- IBC Tanks: 1000 kg per tank (20 MT per 20-foot container)
6. Environmental Responsibility
Dithiophosphate 25 is designed to meet modern environmental standards:
- The majority of the reagent is tied up with the concentrate and destroyed during further processing.
- Proper tailings management ensures that residual traces are not released into natural water systems.
- Adherence to environmental protocols makes it a responsible choice for sustainable mining operations.
