Lithium Hydroxide or Lithium Carbonate Product
Conventional
Process
65-75% Lithium Recovery
Complex Process
High Sludge Production
Yielding of Low-Value Products
SEM
Process
85-95% Lithium Recovery
Simple Process
Minimal Sludge Discharge
Production of High-Value Core Materials
Brine Pool And Wastewater
Lithium Production From Brine & Wastewater
Harvesting Lithium From Brine Pool
-
RAW LITHIUM BRINElithium in the brine Treated Brine (Lithium-free) LITHIUM CONCENTRATE1Lithium ions are absorbed selectively to solid Materials highly selective for lithium (acts like a chemical filter). 2Brine without lithium leaves the system for injection back into the reservoir. 3Stripping fluid removes the lithium ions to produce a high grade, high purity concentrate.
Lithium Recovery from Lithium-Laden Wastewater
-
Proprietary sorbent highly selective for Lithium RAW LITHIUM BRINE Treated Brine (Lithium-free) to be Re-injected LITHIUM CONCENTRATE TO BE REFINED
- Lithium Production from Low-Grade Salt Lakes and Lithium-Containing Wastewater
- Low Transmembrane Differential Pressure
- Daily Lithium Production
- Land Degradation and Environmental Pollution Issues
- Eliminates the Need for Salt Farms as Lithium Enrichment Sites (reduces investment cost)
