Abstract

Abstract

The experimental results for liquid-liquid extraction show that the content of RE₂O₃ in last enriched solution can reach 130g/l or so. This solution is evaporated to produce the solid crystal of mischmctal chloride. The experimental conditions are as follows:extractant is D₂EHPA (70%), there is 3g/1 of RE₂O₃ in leaching solution, and the counter solution is 5N HCI.
