Recovery of scandium, yttrium and lanthanides from zircon sand. This is a process for extracting scandium from zircon ore. It utilizes feeding zircon sand to a fluidized bed chlorinator at about 1000° C. to produce a vaporous (principally zirconium and silicon chlorides) phase and a solid residue and recovering scandium from the solid residue.

A process for recovering scandium economically with high efficiency by concentration and separation from an oxide ore containing nickel and a small amount of scandium as well as a large amount of iron and/or aluminum comprises the steps of acid leaching the oxide ore under a high-temperature, high-pressure oxidative atmosphere while restraining leaching of the iron …

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.
