Ekosolve™️ Lithium Extraction

Recharge Resources and Ekosolve Technology

 
Recharge 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. Recharge has a Argentina wide licence for the utilization of Ekosolve™ technology which is currently contemplated for the company’s Pocitos 1 Project.
 
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.

Benefits of EKOSOLVE 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
 
Multi Phase Plant contemplated for the Pocitos 1 Project with the goal of producing 20,000 tonnes annually.
