## Abstract BACKGROUND: Di‐(2‐ethylhexyl)phosphoric acid (D2EHPA, H~2~A~2~) has been used extensively in hydrometallurgy for the extraction of rare earths, but it has some limitations. Synergistic extraction has attracted much attention because of its enhanced extractabilities and selectivities. In
