Extraction of Scandium from Lateritic NickelCobalt Ore Leach Solution by Ion Exchange: A Special Study and Literature Review on Previous Works
Scandium is a chemical element with the symbol Sc and atomic number 21. A silverywhite metallic dblock element, it has historically been classified as a rareearth element, together with yttrium and the was discovered in 1879 by spectral analysis of .
The Nyngan Scandium Project is located approximately 25km west of the town of Nyngan and 500km northwest of Sydney, New South Wales (NSW), Australia. It incorporates part of the Exploration Licence (EL) 6009 and the entire EL 6096, covering a total area of approximately 9,000ha. Touted to be the ...
In the past decade, various scandium recovering technologies have been developed in China because of the increasing use of scandium in hightech 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.
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.

Acid leachingsolvent extraction is an effective process to extract scandium from scandiumbearing resources. This study was aimed to investigate the extraction behavior of metal ions, including ...
Complex compounds of 2,2''dipyridyl and 1,10phenanthroline are useful in various electroanalytical methods (extraction voltammetry, direct and indirect variants of potentiometry and coulometry, amperometric and conductometric titration).
Solvent extraction of scandium occurs by contacting the PLS with an organic phase containing a primary amine (Primene JMT) 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.
Due to the complex process for separation and purification of Sc from these ores, Sc is a kind of very expensive metals with high prices, which seriously obstructs its widely applications. As scandium and zirconium are commonly associated elements, Zr is a kind .
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.
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),
In this study, the optimization of scandium extraction from bauxite residue with sulfuric acid is investigated using Taguchi methodology. Based on previous studies, acid molarity, leaching time, solid/liquid ratio, and reaction temperature were selected as .
Taking into account scandium limited availability coupled with its high demand in modern technology, bauxite residue could be considered as a potential resource for scandium recovery. In this study, the optimization of scandium extraction from bauxite residue .
Extraction of Scandium (III) from acidic solutions using organophosphoric acid reagents: A comparative study Article (PDF Available) in Separation and Purification Technology · .
In this study, the feasibility and mechanism of recovering scandium from a scandiumrich 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.
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, liquidsolid ratio, leaching temperature and leaching time is investigated with chemical analysis through the orthogonal experiment. The results show that the optimum leaching conditions is ...
Platina Scandium Project – Key Project Parameters: Way Forward – Platina Resources is currently progressing with Mining Licence Application (MLA), Environmental Impact Assessment, Development Applications (mine and process plant), as well as securing offtakes and financing for the project. On 9 May 2019, the company informed to have lodged ...
A study was carried out for recovery of scandium from KOH submolten 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.

Based on leaching experiments of complex silicate ore contenting scandium, the research has adopted extraction to concentrate scandium and separate impurity. The emphasis of this reaserch is the impact factors, so the experiments including extractant concentration, organic aqueous ratio, mixing time, organic phase washing, organic phase reextraction, have been conducted.
However, it is very difficult to enrich this ore, because of the poor beneficiability of silicate and dispersed distribution of scandium minerals. This paper has focused on magnetic separation processes for the preconcentration of poor magnetite associated with scandium oxide ore, according to the composition and occurrence state of scandium.
The results show that the extraction rates of Sc can reach up to 95%.The removing of Fe,Mn and Ti can be reached %, % and % antiextraction rates from organic phase with NaOH reach up to % with effective separation from Fe,Mn and Ti. ...
