Seeyon®M3272/3301/3302 is a series of high-performance phosphonic acid extractants designed for the hydrometallurgical processing of non-ferrous metals, including copper, zinc, cobalt, nickel, cadmium, gold, silver, platinum group metals, and rare earths. These extractants are particularly effective in nickel-cobalt separation, while also capable of extracting other metal ions across a wide pH range.

The Seeyon®M3272/3301/3302 series is fully miscible with common aromatic and aliphatic hydrocarbon diluents, ensuring smooth phase separation and process efficiency. They exhibit excellent thermal stability and resistance to hydrolysis, making them suitable for high-temperature hydrometallurgical operations.

Recommended dosage: 1/5 to 1/3 of the extraction solution.

Key Advantages:

• High selectivity for nickel-cobalt and other valuable metals

• Excellent stability in varied pH and high-temperature conditions

• Compatible with common diluents for efficient extraction

• Enhances metal recovery and process reliability
