IMPROVED METHOD OF RECOVERING PALLADIUM FROM OTHER METALLIC ELEMENTS PRESENT IN A NITRIC AQUEOUS PHASE USING MALONAMIDE EXTRACTORS |
| abstract |
The present invention relates to a process for recovering palladium from a nitric aqueous phase comprising a nitric acid concentration of at most 3 mol.L -1 and which contains, in addition to palladium, at least one other metal cation whose valency is greater than or equal to 2, said process comprising an extraction step with an organic phase comprising at least one sulfur-free malonamide as extractant, at least one step of washing the organic phase with an aqueous phase with an O / A ratio greater than or equal to 4 and a step of removing the palladium by an aqueous solution. |
