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.
