Description

Sodium O,o-Diisopropyl Dithiophosphate is an organophosphorus compound widely used as a high-performance collector and flotation agent in mineral processing. Its primary value lies in its exceptional selectivity and strong collecting power for sulfide minerals, particularly in the recovery of copper, lead, and zinc ores. This chemical is essential for mining and metallurgical operations seeking to improve mineral recovery rates and concentrate grade. Its utility also extends to specialized applications as a corrosion inhibitor and an intermediate in organic synthesis.

Application

• Mineral Flotation Agent: A primary collector for the selective flotation of sulfide minerals, including chalcopyrite, galena, and sphalerite.
• Copper Ore Processing: Enhances the recovery and grade of copper concentrates in froth flotation circuits.
• Lead-Zinc Separation: Used in complex ore beneficiation to improve the separation efficiency of lead and zinc sulfides.
• Corrosion Inhibition: Serves as an effective additive in lubricants and industrial fluids to protect metal surfaces.
• Chemical Intermediate: Utilized in the synthesis of other organophosphorus compounds for agrochemicals and specialty chemicals.
• Metal Extraction Hydrometallurgy: Acts as a solvent extraction reagent for the recovery of precious and base metals from leach solutions.

Quality Control

Our Sodium O,o-Diisopropyl Dithiophosphate is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability for industrial applications. Each production lot undergoes rigorous analytical testing, including assay, impurity profiling, and physical property verification. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with agreed specifications and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance. Keep away from strong oxidizing agents.
