The next generation of extraction excellence
- Ekosolve Technology 

Spey Resources is committed to the process of timely, competitive cost, environmentally sensitive extraction practices. Utilizing Ekosolve™ Technology, this revolutionary process based on well known solvent exchange principles reduces capital and operations costs and accelerates project start up, avoiding 12-18 months of pond construction and evaporation.

With high recoveries of lithium from brines, this process produces battery grade lithium carbonate. Ekosolve™ circumvents problems of brine contaminants being expensive and difficult to remove, particularly magnesium. Ekosolve™ involves four simple stages over three hours to produce lithium chloride which when sodium carbonate is added produces battery grade lithium carbonate.

SOLVENT EXCHANGE CONCENTRATION PROCESS FROM PUMPED BRINES

  • No ponds required – saving $100m in capex

  • Three hour residence time – 8 cycles every 24 hours – 99.5% purity Li2CO3

  • High Battery grade lithium produced – no further processing needed

  • 95% recovery of Solvent Extraction chemicals – reduction in opex

  • Process patented by University of Melbourne and Ekos Research – low patent cost as a percentage of revenue

  • Fast construction time –modular construction – small footprint

  • Minimal water use – brines sent back to salar with lithium extracted, no pollution

  • First phase set up of small 500 tonne plant, laboratory for processing and brine management - $3.5m USD

  • Concentrated lithium brines confirmed by Oxygen 14 dating vs fresh waterInventors involved in project from inception
