Tóm tắt

Solvent extraction of La from acidic chloride solutions has been carried out using 2-ethylhexyl phosphonic acid mono-2-ethylhexyl.ester (PC88A) as the extractant. The features of light rare earths extraction (La, Ce and Pr) with PC88A-IP2028 were determined. The parameters of the solvent extraction process for La recovery have been calculated using a static calculation. Based on the parameters obtained, the extraction of La(III) was carried out using mixer-settler equipment. La(III) oxide was successfully separated from light rare earths from Dong Pao (Lai Chau) with the purity of 99.2 percent.
