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 ...
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 ...
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 pre-concentration of poor magnetite associated with scandium oxide ore, according to the composition and occurrence state of scandium.
Australia's largest, advanced scandium mining project, with Definitive Feasibility Study commenced simple metallurgy –off-the-shelf solvent extraction processing plant consistently achieving >97% recovery of scandium Similar resource tonnage and mining head grades of cobalt, nickel and scandium as Clean TeQ's Syerston ore body 10
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 ...
Extraction of Scandium (III) from acidic solutions using organo-phosphoric acid reagents: A comparative study Article (PDF Available) in Separation and Purification Technology · .
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.
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.
Preliminary extraction of scandium and direct input of extractants into flame allow us to increase selectiv-ity and sensitivity of the analysis. Practically full extraction of the complex of scandium from hydrochloride medium was used for develop-ment of extraction-atomic-absorption determination of scandium in soils. Selective technique for ...
Reno, Nevada--(Newsfile Corp. - February 21, 2019) - Scandium International Mining Corp. (TSX: SCY) ("Scandium International" or the "Company") is pleased to provide an update on our US Patent ...
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.
The Nyngan Scandium Project is located approximately 25km west of the town of Nyngan and 500km north-west 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 ...
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.
Jan 25, 2019· In the present study, the crystallization of an ammonium scandium fluoride phase by cooling and antisolvent crystallization techniques is presented. Cooling crystallization gave a low yield of ammonium scandium hexafluoride, (NH 4) 3 ScF 6, below 50% at the lowest temperature of 1 °C investigated. Antisolvent crystallization using ethanol gave ...

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'
Jul 02, 2015· A method for separating and refining scandium according to the present invention is a method for separating and refining scandium by selectively extracting the scandium from a solution produced by applying a leaching treatment to ores and intermediates containing the scandium using an acid solution or the like.
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.
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 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.
