Abstract

Disclosed is a process for extracting gold ions from an aqueous phase containing gold ions. The process comprises contacting the aqueous phase with an extractant phase consisting of or comprising an ionic liquid (IL) under liquid-liquid extraction conditions for a time sufficient to allow transfer of at least some of the gold ions from the aqueous phase to the extractant phase; and separating the extractant phase from the aqueous phase.
