✅ Dithiophosphate 3719

Dithiophosphate 3719 is a high-strength, high-selectivity dithiophosphate flotation collector designed for gold, silver, copper, lead, zinc, and complex polymetallic sulfide ores.
Recognized for its powerful collecting capability, excellent selectivity, and superior performance in refractory and finely disseminated ores, Dithiophosphate 3719 is widely used in advanced flotation circuits requiring both high recovery and optimized concentrate grade.

Compared with other dithiophosphates, Dithiophosphate 3719 provides one of the strongest adsorption strengths in the series while maintaining precise control over pyrite and iron sulfate mineral flotation. It is ideal for operations seeking maximum metallurgical efficiency in challenging ore environments.

Engineered for modern concentrators, Dithiophosphate 3719 offers:
• Very strong collecting power for chalcopyrite, galena, sphalerite (activated), and precious-metal sulfides
• Outstanding selectivity against pyrite, pyrrhotite, and unwanted gangue minerals
• Superior recovery in refractory, oxidized, or ultra-fine sulfide ores
• High efficiency in Cu/Pb and Cu/Zn differential flotation circuits
• Cleaner concentrate grade with lower impurity levels
• Robust performance across a broad pH range and variable pulp chemistry
• Effective booster action when combined with xanthates or thionocarbamates

Dithiophosphate 3719 is especially effective in:
• gold–silver flotation, including refractory and fine-particle gold
• copper–lead and copper–zinc differential flotation
• polymetallic sulfide ores with complex mineralogy
• partially oxidized copper and precious-metal ores
• flotation circuits requiring both strong collection and high-grade selectivity
