The Xolobeni mine is the country's primary source of titanium as it has significant deposits of ilmenite, titanium-iron ore, and zircon. 6. Canada . Ilmenite Reserves: 31 million metric tons .
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.
Scandium was recovered from titanium, zirconium, cobalt, and nickel process streams. China, the Philippines, and Russia were the leading producers. Prices quoted for scandium oxide in the United States decreased ... Scandium lacks affinity for the common ore-forming anions; therefore, it is widely dispersed in the lithosphere and
Lei et al. devised a way to extract scandium and titanium from red mud leachate solution using a neutralization precipitation and acid leaching methodology as shown in Figure 21. They found that the precipitation efficiencies of scandium and titanium were 93.74% and 99.47%, respectively, under optimal conditions.
Scandium is widespread over the earth and can be found as trace elements in more than 800 different metal ores (the most common minerals are reported in Table 12.1). Scandium oxide is the most abundant element in a mineral called thortveitite of composition R 2 Si 2 O 7, where R is Sc, Y, or other rare earth metals. Thortveitite contains 30% ...
The scandium-containing titanium ore in Yunnan contains TiO2 with grade of 12.68%, Fe with grade of 31.65%, and Sc2O3 with grade of 92 g/t. Scandium is mainly distributed in titanaugite ...
As a result of its low concentration, scandium is produced exclusively as a byproduct during processing of various ores or recovered from previously processed tailings or residues. His torically, scandium was produced as byproduct material in China (iron ore, rare earths, titanium, and zirconium), Kazakhstan (uranium), the Philippines (nickel),
Simplicity and integrity of the unit operations, reagents availability and low cost and the high recovery of Ti and Sc are the main advantageous of this process. The overall titanium recovery in this study has reached to 78.5 % with the purity of 92 %. The total recovery of scandium was 83.8 %, producing a hydroxide precipitate of 1125 ppm Sc.
Ceramics - The addition of about 20% scandium carbide to titanium carbide results in a doubling ... primarily iron ore, but it also contained scandium, uranium and other radioactive minerals. The scandium resource was estimated to be 7.9 M tonnes grading 105 ppm scandium, and the mine was believed to be the only primary scandium mine in ...

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.
Scandium concentrate and titanium dioxide wastewater (TDWW) all belong to waste, especially TDWW belongs to hazardous waste, it is urgent to find a more efficient and safer treatment method to deal with them, and both waste acid and waste ore contain scandium.

Titanium exists in the ore mainly as ilmenite, accounting for 95.35% of the total titanium content, with the remaining titanium present in the form of titanomagnetite and sillimanite. In addition, vanadium is not only present in isomorphous association with ilmenite and titanomagnetite but also exists in small amounts in the form of silicates.
