DY366 is an organophosphorus chelating reagent for scandium recovery from dilute streams. It separates scandium from nickel, cobalt and iron in HPAL laterite circuits, where scandium reports to the iron-aluminium slag and waste liquors, and it also works on red mud, titanium dioxide waste acid and tungsten refinery slag.

- 01The feed assay determines whether a concentration step is needed before extraction.
- 02Scrub conditions are set from the iron-to-scandium ratio in the loaded organic.
- 03Stripping gives a scandium concentrate that is refined to scandium oxide.
