High-efficiency Extractant for Separation of Nickel and Cobalt-AD290

An application for the high-efficiency extractant AD290 is in the separation of nickel and cobalt. It is widely employed to extract nickel from ores, concentrates, and solution streams during hydrometallurgical processes.  

It is also suitable for the extraction and separation of rare earths: gallium (Ga), indium (In), molybdenum (Mo), germanium (Ge), zirconium (Zr) and other metals.

Packing: 200 kg/plastic barrel.

Storage: Handled with care during transportation to prevent impact, prohibiting open flame. Stored in a cool, ventilated and dry warehouse, ensuring waterproof and rainproof.

Chelation: AD290 acts as a chelating agent, forming stable complexes with nickel ions present in an aqueous solution. The chelation process involves the formation of chemical bonds between AD290 molecules and the metal ions, particularly nickel.

Selective Extraction: AD290 exhibits a high selectivity for nickel over cobalt, allowing for the preferential extraction of nickel from a mixed metal solution. When AD290 is dissolved in an organic solvent, it creates an interface between the aqueous and organic phases.

Solvent Extraction: The aqueous solution containing nickel and cobalt ions is mixed with the AD290 organic extractant. AD290 selectively interacts with the nickel ions, forming soluble complexes that are transferred into the organic solvent phase.

Phase Separation: After the extraction, the organic phase containing the nickel-AD290 complexes is separated from the aqueous phase. Various techniques such as settling, centrifugation, or decantation are employed to achieve phase separation.

Stripping and Recovery: The nickel ions can be recovered from the organic phase by employing suitable stripping agents or solutions. These agents break the complexes formed with AD290, resulting in the release of nickel ions into a new aqueous solution or suitable medium.

Recycling: The organic phase containing AD290 can be recycled by removing impurities and reusing it in the extraction process, contributing to cost-effectiveness and sustainability.
