Extraction of Scandium from Lateritic Nickel-Cobalt Ore Leach Solution by Ion Exchange: A Special Study and Literature Review on Previous Works
Review of the scandium assay data across the deposit shows that it is pervasively distributed at elevated grades (>180ppm scandium) throughout the lateritic profile, but generally preferentially around the periphery of the central dunite complex. The bulk of the scandium mineralisation is present within the OVB, TZ, and GZ.
Experimental Study on Extraction of Scandium from Complex Silicate Ore ... G. F. Zhang et al., "Experimental Study on Concentrating Scandium by Leaching from Associated Scandium Ore", Advanced Materials Research, Vols. 734-737, pp. 1033-1036, 2013.
Experimental Study of the Static and Dynamic ... Complex on Extraction Efficiency of REEs from ... as well as scandium and yttrium [1]. Scandium and yttrium are considered REEs since they occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. REEs are cerium (Ce), dysprosium (Dy),
This research is concerned with the solvent extraction into chloroform of the lanthanides, using 2,5-dimethyl-2-hydroxyhexanoic acid (DMHHA). This acid is the first ..cap alpha..-hydroxy aliphatic acid to be studied as an extracting agent for the lanthanides.
Oct 26, 2012· Toward this end, an acid leaching and solvent extraction system has been developed and optimized to extract scandium from wolframite residue. With the technique, the scandium oxide content in the resultant scandium hydroxide can reach 70–78 percent.
Complex compounds of 2,2'-dipyridyl and 1,10-phenanthroline are useful in various electroanalytical methods (extraction voltammetry, direct and indirect variants of potentiometry and coulometry, amperometric and conductometric titration).
Nigel Ricketts, our Process Engineering expert and Manager of Studies in Queensland, recently presented a paper at TMS 2019 in Texas on scandium solvent extraction. If you are a process engineer interested in scandium processing techniques, or a mining professional looking at scandium opportunities, this condensed version of the technical paper might be of interest to you.
In the past decade, various scandium recovering technologies have been developed in China because of the increasing use of scandium in high-tech products and the demands of the international scandium market. Solvent extraction is reported to be one of the most effective techniques to extract scandium from various resources.

Optimizing Conditions for Scandium Extraction from Bauxite Residue Using Taguchi Methodology Article (PDF Available) in Minerals 9(4):236 · April 2019 with 85 Reads How we measure 'reads'
The scandium concentrate used in the leaching experiment was obtained from the rare earth ore containing scandium in Yunnan Province, the sample used in experiment is leaching liquid containing scandium which the content of scandium is 3.6g/t, with complex impurity composition. The main influencing factors of extraction in hydrochloric acid solution were acidity, mixing time, phase ratio etc ...
A study was carried out for recovery of scandium from KOH sub-molten salt (SMS) leaching cake of fergusonite. Major metals in the cake were rare earths (RE), K, Th, U and Ca, and minor metals were Pb, Nb, Ta, Ti, Fe, Si, Sn, Al, Bi and Mn.
Scandium is concentrated in the dust during TiO2 chlorization. The dust can be used as a raw material from which Scandium is extracted. Scandium leaching conditions such as leaching acid concentration, liquid-solid ratio, leaching temperature and leaching time is investigated with chemical analysis through the orthogonal experiment. The results show that the optimum leaching conditions is ...
Jun 23, 2016· In the scandium extraction step, scandium values are extracted from a scandium source with an organic solvent, thereby obtaining a scandium-loaded organic solvent. The scandium source may be, for example, a leachate, an industrial byproduct, or a metal sludge, and will typically contain both scandium and iron ions, in addition to other metal ions.
The results show that the extraction rates of Sc can reach up to 95%.The removing of Fe,Mn and Ti can be reached 99.1%, 99.4% and 99.5% respectively.The anti-extraction rates from organic phase with NaOH reach up to 99.7 % with effective separation from Fe,Mn and Ti. ... "Experimental Study on Extracting Scandium from HCl Leachate of ...
In this study, the feasibility and mechanism of recovering scandium from a scandium-rich material were investigated based on the acid leaching and solvent extraction process. The results showed that phosphoric acid had an advantage in separating scandium from impurities over hydrochloric acid, sulfuric acid and nitric acid.
Solvent extraction of scandium occurs by contacting the PLS with an organic phase containing a primary amine (Primene JM-T) dissolved in a kerosene (Shellsol D70) in three counter current extraction stages. A scandium sulphate complex ion leaves the aqueous phase and loads onto the amine.
