Description

Sodium O,o-Di-sec-Butyl Dithiophosphate is an organophosphorus compound widely utilized as a high-performance specialty chemical additive. Its primary value lies in its effectiveness as a collector and frother in mineral flotation processes, particularly for sulfide ores, enhancing metal recovery rates and selectivity. This product is essential for industries involved in mining and metallurgy, where it serves as a critical reagent for the extraction of copper, lead, zinc, and other valuable metals.

Application

• Sulfide Ore Flotation: A primary collector and frother for the beneficiation of copper, lead, zinc, and nickel sulfide minerals.
• Precious Metal Recovery: Used in the flotation circuits for gold and silver-bearing ores to improve concentrate grade.
• Industrial Lubricant Additive: Functions as an anti-wear and extreme pressure (EP) additive in metalworking fluids and industrial lubricants.
• Corrosion Inhibitor: Employed in water treatment formulations and cooling systems to protect metal surfaces.
• Polymer Stabilizer: Acts as an antioxidant and stabilizer in certain polymer and rubber formulations.
• Chemical Intermediate: Serves as a key precursor in the synthesis of other organophosphorus compounds for agrochemicals and specialty chemicals.
