Lithium extraction reagents for brine and recycle streams
Lithium extractants for salt-lake brine, mineral leach solutions and spent battery recycling streams with high sodium and magnesium background.
Lithium reagent selection depends on the sodium, magnesium and calcium background and on the target lithium purity.
Process context
Where the reagent sits in the circuit
01
Brine concentration
Brine is concentrated and polished before lithium is transferred to the organic phase.
02
Selective extraction
DY316 loads lithium while limiting sodium and magnesium transfer into the organic.
03
Strip to lithium chloride
Stripping yields a lithium chloride or sulphate stream for further purification.

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 lithium tenor, acidity and the main competing ions. A model recommendation follows from those values.
