Rio Tinto acquires high-grade scandium project in Australia
The project, near Condobolin in central New South Wales, comprises a long life, high-grade scalable resource that could produce up to 40 tonnes per annum of scandium oxide, for an estimated period of 30 years. Rio Tinto currently produces scandium oxide from titanium dioxide production waste streams at Sorel-Tracy in Quebec.Scandium is usually associated with scattered lithophile elements of Ni-Co laterite, bauxite, W-Sn deposits, titanium ore, uranium ore, zirfesite and rare earth elements as homomorphous impurities (Narayanan et al., 2018, Nie et al., 2018, Qiu et al., 2019, Roosen et al., 2016, Ulrich et al., 2018, Wang et al., 2020, Wen et al., 2017, WangRecovery of scandium and aluminum from limonitic

Extraction and Utilization of Valuable Elements from Bauxite
Bauxite is the ideal raw material for the manufacturing of alumina. Aside from the primary constituents of aluminum and silicon, bauxite is frequently coupled with many valuable elements such as gallium (Ga), titanium (Ti), scandium (Sc), and lithium (Li). The bauxite residue and circulating spent liquor in alumina production typically include The elements contained in the scandium ore from Madagascar, adapted from . 3.2.

Recovery of scandium from red mud by leaching with titanium white waste
Recovery of scandium (Sc) from various wastes is generally one strategy to solve potential supply shortage problems of Sc. This work proposes a synergistic process for co-recovery of Sc by using the acid titanium white waste acid (TWWA) to leach the basic red mud, to which the acidity was adjusted with concentrated sulfuric acid when necessary. A kind of method of from titanium ore, extracting scandium.Titanium ore is infeeded in about 1000 ℃ fluidized bed chlorination stove generating a vapour phase and solid residue, and from residue, reclaim scandium.Although the sublimation temperature of Scium trichloride is lower, the scandium that content is very low still is concentrated in the residue, makes From titanium ore, reclaim scandium, yttrium and lanthanide

A Novel Approach for Separation and Recovery of Titanium, Scandium
At present, acidic wastewater is directly neutralized with lime or limestone, which wastes resources such as titanium, scandium, and iron and generates a great deal of solid waste. This study proposes a novel approach for the separation and recovery of titanium, scandium, and iron from acidic wastewater and red gypsum utilization. The The ore is used to produce high-quality titanium dioxide feedstock, pig iron, steel and metal at RTFT’s metallurgical complex in Sorel-Tracy, Quebec. Together, the sites employ over 1,600 people. RTFT has operated in Quebec for 70 years and pioneered the process of removing iron from ilmenite.Rio Tinto opens new scandium plant in Canada

Production of scandium radionuclides for theranostic
In the frame of “precision medicine”, the scandium radionuclides have recently received considerable interest, providing personalised adjustment of radiation characteristics to optimize the efficiency of medical care or therapeutic benefit for particular groups of patients. Radionuclides of scandium, namely scandium-43 and scandium-44 The European Union and several countries/regions classified the rare-earth elements (REEs), such as lanthanum, cerium, neodymium, and scandium, as critical due to the risk of supply interruption. For this reason, the growing demand for REEs has resulted in forgotten reserves receiving economic interest.

Recovery of scandium and aluminum from limonitic
Currently, scandium is mainly recovered from by-products of titanium and uranium extraction (Chen et al., 2021). In China, scandium is mainly extracted from titanium white waste acid via a two-step solvent extraction process or scandium-bearing chlorinated fume, which results from the extraction of titanium through a pyrometallurgical processScandium minerals with high scandium content, such as thortveitite and lolbeckite, are mainly dispersed in the thortveitite-rich pegmatites in Madagascar and Norway (Hedrick, 2010a).One of ores in Norway is a double silicate of scandium and yttrium with the formula of 2SiO 2 Y 2 O 3 Sc 2 O 3 (Baptiste, 1959).Another ore in Madagascar Metallurgical processes for scandium recovery from various resources
