Separation of lithium, cobalt and nickel from spent

Lithium, cobalt and nickel are the main constituents of lithium-ion battery cathodes in the so called “nickel-cobalt-aluminum” (NCA, cathode made of L i N i 0.8 C o 0.15 A l 0.05 O 2) batteries . As a result, concern is rising about the future availability of these metals. For instance, cobalt is already considered as a critical material by the European Commission, while lithium is a near

Separation of nickel from cobalt in sulphate medium by ion

Separation of nickel from cobalt in sulphate medium by ion exchange. Hydrometallurgy, 13: 33--44. A process is described for the selective removal of nickel from acidic cobalt sulphate solution with Dow ion exchange resin XFS 4195. The results of laboratory fixed-bed (25 mm diameter by 1.5 m deep) studies are presented, showing that raffinate Co/Ni ratios of ~ 500:1 can be obtained from feeds

Separation of Nickel from Liquid Media DuPont

While solvent extraction (SX) can be used to recover nickel, novel selective ion exchange (IX) resins are making it possible to isolate and purify nickel at lower cost and in more environmentally sustainable ways. AmberSep™ M4195 Chelating Resin is used to facilitate the difficult separation of nickel from cobalt in cobalt refining.

Recover Cobalt in Copper Leach Solution by Ion Exchange

The cobalt recovery process consists of four major unit operations: (1) ion exchange (loading and elution) to extract and concentrate the cobalt, (2) purification of the ion-exchange eluates using solvent extraction to remove coextracted impurities, (3) a second solvent extraction operation to separate the cobalt and nickel and concentrate the cobalt, and (4) cobalt electrowinning to produce a

Separation of copper, nickel, and cobalt by ion

Separations of copper from nickel, and copper from cabalt were attempted by use of cation exchange resin. The same apparatus, resin and separatory technique as described in the first report of this series were used except that 2.5M sodium chloride was used for liberation of nickel and cobalt from the resin. Nickel and cobalt were determined by titration with EDTA solution, using murexide as an

Cobalt Sorption in Ion-Exchange Column

Thus, the ion-exchange investigation was directed toward the use of a continuous, fluidized-bed, ion-exchange column. The Bureau-developed MCIX column was chosen for the cobalt recovery studies since previous work using this column to extract uranium from low-grade solutions had demonstrated its utility in reducing resin inventories when compared to fixed- bed systems. Ion-exchange resin Dow
