meant >98.6 % cobalt extraction was required, depending on the extent of nickel extraction. Basic operating parameters were used; pH 5.1 – 5.5, temperature of 60°C, retention time of 5 minutes and organic continuous continuity at various organic to aqueous (O:A) ratios. Caustic was used for maintain the pH in the mixer. This test was completed as a two stage series parallel test. The first ...

There is considerable interest in the extraction separation of copper, nickel, and cobalt in the ammoniacal liquors, . Although Cyanex302 presents a good extraction potential due to its strong coordination ability with metal ions, the separation of Cu(II) and Co(II) in the ammoniacal media is very difficult. In order to clearly present the regulation role of Cyphos IL101 on the extractability ...

Solvent Extraction of Cobalt SX

Traduire cette page

It is known that cobalt (III) will not be extracted by LIX64N during nickel and copper extraction, but remains in the raffinate. The raffinate is recycled to the leach stages, thus cobalt will build in concentration unless removed. Eventually a point would be reached where the cobalt concentration would reduce the leaching power of the solution.
