Dithiophosphate 25
Dithiophosphate 25 is a composite mineral processing reagent that combines both collecting and frothing functionalities. It presents as a blackish-brown oily liquid with a primary active ingredient—xylenol dithiophosphoric acid—content ranging between 60% and 70%. Its density at 20°C measures 1.17-1.20 g/mL. The reagent exhibits considerable chemical stability and displays differentiated collecting behaviors across various pH media. It is widely employed in the flotation separation of polymetallic sulfide ores, demonstrating particularly notable effectiveness in the processing of lead, copper, and silver ores.

Characteristics & Applications
- The reagent displays strong collecting power for lead, copper, and silver sulfide minerals, and it is also effective on activated zinc sulfide ores. Its molecules adsorb onto mineral surfaces through hydrophobic groups, significantly enhancing mineral hydrophobicity and promoting the attachment of target minerals to air bubbles, thereby increasing the recovery of valuable components.
- Its behavior varies significantly with pH: in alkaline conditions, it exhibits weak collecting power toward pyrite, favoring the preferential flotation and separation of lead and zinc minerals. In neutral to acidic media, it acts as a powerful non-selective collector for most sulfide minerals.
- The inherent frothing properties of Dithiophosphate 25 reduce the need for additional frothing agents. In specific flotation circuits, it aids in forming a foam layer of suitable size and stability, thereby improving separation efficiency. Under certain process conditions, it also shows auxiliary collecting effects for some heavy metal oxide ores.
Key Advantages
- High-efficiency collection of lead, copper, silver, and activated zinc sulfide ores, with broad applicability across various mineral types.
- Excellent selectivity in alkaline environments, facilitating the suppression of pyrite and separation of target minerals in complex ores.
- Applicable under specific conditions for oxide ore flotation, expanding its range of use.
