Case study
500 L/h Lithium-Extraction Membrane Separation and Concentration Pilot
This 500 L/h pilot platform evaluates salt-lake brine and lithium-bearing ore-leach liquor. PEK tubular membranes, resin adsorption, nanofiltration and reverse osmosis are combined to validate clarification, selective separation and concentration.
Project overview
This 500 L/h pilot platform evaluates salt-lake brine and lithium-bearing ore-leach liquor. PEK tubular membranes, resin adsorption, nanofiltration and reverse osmosis are combined to validate clarification, selective separation and concentration.
Process route
Conditioning, softening and PEK clarification combined with resin adsorption, NF salt separation, RO concentration and downstream lithium-recovery stages
Process roles
Tubular membranes provide solid-liquid separation; adsorption and NF perform the corresponding selective-separation duties, and RO provides concentration and water recovery. The platform interfaces these membrane stages with downstream lithium precipitation and mother-liquor treatment for scale-up evaluation.
