re-extraction [obsolete]
https://doi.org/10.1351/goldbook.R05225
Since the prefix 're' can signify 'back' as well as 'again' this term is ambiguous and should be avoided, except where the process of extraction(e.g. from aqueous solution to an organic phase) in a single direction is repeated (following stripping). It should not be used as a synonym for stripping or back-extraction.
