Name: Solvay CYANEX 301
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Solvay CYANEX 301

Highly selective extractant for divalent transition metals—especially Ni²⁺ and Co²⁺—under acidic conditions.
Superior stripping efficiency with dilute acid, enabling low reagent consumption and simplified process recovery.
Excellent chemical and radiolytic stability in aggressive hydrometallurgical environments.
Low aqueous solubility and minimal third-phase formation, ensuring robust phase separation and operational reliability.
Compatible with standard industrial diluents (e.g., kerosene, Shellsol® D70) without requiring modifiers.

Typical Applications Of Solvay CYANEX 301

Cobalt–nickel separation in laterite and sulfide ore processing.
Purification of battery-grade nickel and cobalt cathode precursors (e.g., for EV lithium-ion batteries).
Recovery of cobalt from spent lithium-ion battery leachates.
Removal of copper and zinc impurities during nickel electrolyte purification.
Selective extraction in nuclear fuel cycle applications involving actinide/lanthanide separations.
