Support before shipment
01
Feed assessment
Assay, acidity and impurity profile reviewed before a model is proposed.
We read the solution chemistry first: metal tenor, competing ions and the stage where the reagent is expected to work.
02
Sample support
Reagent samples for bench and mini-plant trials.
Samples are shipped with the handling information needed for a representative trial rather than a single shake-out test.
03
Packing and export
Drum, IBC and customer packing with export documentation.
Packing follows the destination and the handling route; documents are prepared with the shipment.
04
Process support
Stage, phase-ratio and scrub guidance during commissioning.
Support covers the questions that appear after the reagent arrives: phase separation, crud, strip acid and stage balance.
Applications
Where extractants run
Ore leach solutionLeach liquors and pregnant solutions
Copper, nickel, cobalt and vanadium are recovered from acidic leach liquors after solid–liquid separation.
DY984N · P204 · P507 · DY272
Salt-lake brineBrine concentration circuits
Lithium is separated from sodium and magnesium background before carbonate or hydroxide production.
DY316
Battery recycle feedRecycling and electrolyte streams
Nickel, cobalt and lithium are recovered from battery recycling liquors and electrolyte recovery streams.

About the supplier
Focused on one category
Shanghai Qilang Industry supplies solvent extraction reagents and nothing else. The catalogue is organised by the metal being separated and by the model line used in that circuit, so a buyer can find the right reagent without reading through unrelated product groups.
Reagent development, batch checks and packing are handled against the flowsheet information shared at enquiry stage.

Notes from the circuit
21 Sept 2026 · Process notes
Choosing a lithium extractant for brine and recycle streams
Lithium sources differ in sodium, magnesium and sulphate background, and that background decides the reagent route far more than the lithium grade alone.
11 Aug 2026 · Process notes
Nickel-cobalt separation: where P507 and DY272 sit in the circuit
The separation reagent is chosen together with the impurity-removal stage ahead of it, because the two decide how clean the cobalt strip will be.

What to send us for a meaningful reagent recommendation
A feed assay, a flowsheet sketch and the target product specification are enough for a first recommendation in most cases.
Tell us your feed
Send the metal, the feed type and the stage you are working on. A model recommendation and a sample route come back from the same place.
