Description

O,o-Dioctyl Hydrogen Dithiophosphate is a versatile organophosphorus compound widely used as an effective extractant and collector in hydrometallurgy. Its primary commercial value lies in its exceptional selectivity for separating and purifying valuable metals from complex ores and solutions. This product is essential for mining and metal refining operations, particularly in the recovery of copper, zinc, and rare earth elements, where it enhances yield and process efficiency.

Application

• Solvent Extraction in Hydrometallurgy: A key extractant for the selective separation and concentration of non-ferrous metals like copper, zinc, and nickel from acidic leach solutions.
• Froth Flotation Collector: Used as a collector agent in the flotation process to improve the recovery of sulfide and oxide minerals.
• Lubricant and Fuel Additive: Functions as an anti-wear and extreme pressure additive in industrial lubricants and greases.
• Chemical Intermediate: Serves as a precursor in the synthesis of other organophosphorus compounds, including pesticides and flame retardants.
• Metal Chelating Agent: Employed in analytical chemistry and wastewater treatment for the chelation and removal of heavy metal ions.
• Corrosion Inhibitor: Provides protective properties in metalworking fluids and industrial cooling systems.
