Solvent extraction process for separation of precious metals |
abstract |
A solvent extraction process for the separation of one or more precious metal species from other precious metal species and possibly also base metal species contained in an aqueous acidic solution of the type produced during the recovery of precious metals from ore or scrap in which the solvent contains an extractant which is a mono-N-substituted amide. Also a mono-N-substituted amide extractant. The extractant permits better separation factors generally and also enables platinum to be extracted before palladium and permits improved extraction of iridium from rhodium. |
