This integrated technology addresses the challenges of high slime content, complex lithium mineral phases, and poor low-temperature adaptability of conventional reagents in hard-rock lithium ores.

Core components:

Lithium flotation collectors BK452 / BK429

Dense media separation (DMS) for pre-concentration and waste rejection

Pre-desliming & dephosphorization

Selective lithium flotation

Key outcomes:

Enables efficient recovery of multiple lithium minerals: spodumene, petalite, amblygonite, lepidolite

Improves lithium flotation recovery by 5–10%

Boosts associated Ta/Nb/Sn recovery by 10–30%

Reduces reagent consumption by 20–30%

Lowers impurity content in lithium concentrate; shortens Ta/Nb/Sn recovery flowsheet; cuts reagent dosage in winter operations

Proven in industrial application：Achieved stepwise recovery of petalite and spodumene, and significantly reducing phosphorus content in spodumene concentrate via simultaneous pre-separation of phosphorus and mica followed by selective lithium flotation. Targeted Complex lithium polymetallic resource development.
