Nickel & Cobalt Extraction Using Organic Compounds

(partial) Leaching of Nickeliferous or Cobaltiferous Sources Using Organic Reagents: using amines, ketones, organic acids, organo-phosphorous compounds, mixtures or organic reagents. Solvent Extraction of Nickel and/or Cobalt from Solutions: using one non-heterocyclic organic compound - using amines, oximes, ketones or aldehydes, organic acids, cyanic acids or derivatives, organic agents containing sulphur, alcohols, phenols or naphthols; using mixtures of acyclic or carboxyclic compounds with organic extractants of different types - using an amine and organic acid, an amine and an anion of organic acid, quaternary ammonium extractant and an oxime or a ketone or a heterocyclic compound, an oxime and an organic acid, an oxime and a sulphonic acid, an oxime and a phenol; using heterocyclic derivatives - using quinoline derivatives, other heterocyclic derivatives; using organophosphorous or organoboron compounds - using alkyl phosphoric acid with another extraction agent, phosphines and/or phosphine-oxides.
