Description

From the batch solvent extraction process, in this work it has been carried out a preliminary study aiming the determination of the optimal operating conditions for zirconium recovery (10 ppm) using alamine 336 (tricaprylylamine) as extractor. The results have shown that the extraction takes place instantaneously (5s of manual agitation) and that at pH around 2.0 the extraction efficiency is up to 98-99% for an aqueous/organic phase volumetric ratio of 10. Based on these results, it is proposed to evaluate the possibility of using of a pioneering technology for metal recovery at low concentrations, using a experimental set-up that associates standard solvent extraction process with liquid-liquid flotation process.
