Description

Sodium Di(Isobutyl)Dithiophosphinate is a specialized organophosphorus compound widely utilized as a high-performance collector and frother in mineral processing. Its primary value lies in its exceptional selectivity and efficiency in the flotation of sulfide ores, enabling superior metal recovery rates and concentrate grades. This chemical is essential for mining operations and metallurgical research focused on copper, lead, zinc, and precious metal extraction.

Application

• Sulfide Ore Flotation: A primary collector for the selective flotation of copper, lead, zinc, and nickel sulfide minerals from complex ores.
• Precious Metal Recovery: Used in the flotation circuits for gold and silver-bearing sulfide ores to improve recovery yields.
• Mineral Processing Research: Serves as a key reagent in laboratory and pilot-scale studies to optimize flotation kinetics and separation efficiency.
• Froth Flotation Aid: Acts as a frother and collector combination, enhancing bubble stability and mineral attachment in flotation cells.
• Industrial Catalyst Intermediate: May be employed as a precursor or ligand in the synthesis of specialized catalysts and coordination complexes.
• Lubricant and Fuel Additive Component: Finds application as an anti-wear or extreme pressure additive in advanced lubricant formulations.

Quality Control

Our Sodium Di(Isobutyl)Dithiophosphinate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed to confirm identity, purity, and critical physical parameters. A comprehensive Certificate of Analysis (COA) detailing assay, moisture content, and other relevant specifications is provided with every shipment to support your quality assurance processes.

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 performance.
