Extraction and Separation of Gallium Using Cyanex 301: Its Recovery from Bayer's Liquor

Gupta, Bina, Mudhar, Niti, Tandon, S. N.·2005·Industrial & Engineering Chemistry Research

Abstract

This paper describes the extraction behavior of Ga(III) along with associated metal ions, viz., V(V), Ge(IV), Ti(IV), V(IV), Tl(III), In(III), Al(III), Fe(III), Cd(II), Zn(II), Ni(II), and Mn(II), by bis(2,4,4-trimethylpentyl)dithiophosphinic acid (Cyanex 301) from different mineral acid media. The effect of different variables such as equilibration time, temperature, nature of diluent, and concentration of acid, metal ion, and extractant on the extraction of Ga(III) has been investigated. The extracting species has been identified. It has been possible to attain separations of Ga(III) from commonly associated metal ions by selective extraction/stripping. The partition behavior has been successfully extended to the recovery of gallium in good yield with high purity from Bayer's liquor. The commercial feasibility of the proposed procedure is supported by the fact that the extractant has good hydrolytic stability, regeneration power, and reasonable loading capacity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
