Scandium extraction reagents
Scandium extractants for recovery from laterite leach liquors, titanium processing residues and red mud streams where scandium is present at low concentration.
Scandium work starts from the feed assay and the main impurity pairs, since concentration steps drive most of the cost.
Process context
Where the reagent sits in the circuit
01
Pre-concentration
Scandium is concentrated from a large dilute stream before solvent extraction.
02
Selective loading
DY366 separates scandium from iron, aluminium and titanium at a controlled acidity.
03
Scrub and strip
Scrub stages remove co-loaded impurities; stripping gives a scandium concentrate for refining.

Questions
Before you specify
What information do you need to recommend a reagent?
The feed assay (metal tenor and main impurities), acidity, the stage where the reagent will work, and the target strip liquor or product specification. A flowsheet sketch helps but is not required for a first recommendation.
Can one model cover several metals?
Some phosphoric ester and phosphinic acid reagents work across nickel, cobalt, vanadium and rare earth circuits, but the loading window is set per application. A model that suits one separation may need a different acidity or modifier in another.
How are samples shipped?
Sample quantity and packing are agreed against the trial scope, then shipped with handling information. Documentation follows the destination country and the carrier requirements.
Send your feed data
Include the scandium tenor, acidity and the main competing ions. A model recommendation follows from those values.
