P204 metal extractant is widely deployed as the core hydrometallurgical agent for the separation, purification, and recovery of non-ferrous, rare earth, and transition metals from acidic leach liquors.
P204 metal extractant, chemically known as D2EHPA (Di-2-ethylhexyl phosphoric acid), it is an industry-standard, high-efficiency liquid-liquid organophosphorus solvent extraction reagent.

The Metallurgical Applications & Extraction Selectivity:
The P204 extraction reagent acts by exchanging a hydrogen ion with a metal cation at controlled pH thresholds. It exhibits variable extraction affinity depending on the solution’s acidity:
1. Cobalt and Nickel Separation: Extensively used in battery-grade chemical refining to separate zinc, copper, and iron impurities from nickel-cobalt sulfate leach liquors.
2. Rare Earth Elements (REE) Processing: Functions as a primary extraction carrier for separating light rare earths (such as Lanthanum, Cerium, Praseodymium, and Neodymium) in sulfate mediums.
3. Indium and Zinc Recovery: Used for high-purity indium extraction from zinc smelting byproducts and secondary slag heaps.
4. Vanadium and Uranium Mining: Widely used for the concentration of uranium and vanadium from sulfuric acid leach solutions.
The Packaging, Storage, and Safety Logistics:
As a specialized chemical reagent, clear handling information builds trust with industrial buyers and safety compliance officers:
1. Packaging Options: Supplied in 200 kg net weight plastic drums or 1000 kg net weight IBC totes (custom bulk ISO tanks available upon request).
2. Storage Protocols: Store in a cool, dry, well-ventilated warehouse away from strong oxidizers, open flames, and direct sunlight. Keep containers tightly sealed.
3. Safety Documentation: Full REACH registration and comprehensive Safety Data Sheets (SDS conforming to GHS standards) are provided with every shipment.
4. Request a Technical Datasheet or Sample: We offer custom dilution and technical consulting for optimizing your SX circuit configuration.
