Description

Sodium o-(sec-Butyl) o-Ethyl Dithiophosphate CAS NO 68739-07-1 is an organophosphorus compound widely utilized as a high-performance collector and frother in mineral flotation processes. Its primary value lies in its exceptional selectivity and efficacy in separating valuable sulfide ores from gangue materials, enhancing metal recovery rates and operational efficiency. This chemical is essential for mining and metallurgical operations focused on the extraction of copper, lead, zinc, and other base metals.

Application

• Sulfide Ore Flotation: Primary collector for the selective flotation of copper, lead, and zinc sulfide minerals.
• Precious Metal Recovery: Used in circuits for recovering gold and silver associated with sulfide ores.
• Complex Ore Processing: Effective in separating mixed or refractory sulfide ores where selectivity is critical.
• Frother Function: Acts as a frothing agent to stabilize the froth layer in flotation cells, improving mineral recovery.
• Industrial Lubricant Additive: Serves as an extreme pressure (EP) additive and anti-wear agent in specialty lubricants and metalworking fluids.
• Corrosion Inhibitor: Used in formulations for protecting metal surfaces in closed-loop water systems or industrial fluids.

Quality Control

Our Sodium o-(sec-Butyl) o-Ethyl Dithiophosphate is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability for industrial applications. Each lot is analyzed against stringent internal specifications for active content, impurity profiles, and physical properties. Certificates of Analysis (COA) documenting purity, assay, and key parameters are provided with every shipment to 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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance and stability. Keep away from strong oxidizing agents.
