MEGA applications for lithium extraction processes
Hard rock / spodumene lithium extraction in Asia, Australia, Africa, Brazil, and North America
We use patented electrodialysis system for the purification of lithium carbonate which reduces the investment and operating costs of obtaining higher lithium concentrations. Try MEGA ED for more effective lithium extraction processes from hard rock and spodumene.
Lithium brine extraction in South America, Canada, and China
Gain high-grade lithium using a unique, cost-effective electrodialysis technical solution implemented into the brine extraction process. MEGA technology lowers the cost of LiCl purification thanks to reduced evaporation and crystallization.
MEGA application for lithium battery recycling companies
Why use electrodialysis in the lithium battery recycling process
The application of electrodialysis in the lithium battery recycling process makes the recovery more effective - including higher purity of the commodity product while decreasing the operating costs. Our unique electrodialysis technology is developed especially for lithium recycling companies.
Lithium is an alkali metal with excellent heat and electrical conductivity. It is highly reactive, therefore does not exist in nature on its own, but only as a constituent of salts or other stable compounds, such as lithium carbonate.
How lithium is mined
Most lithium is mined from either brine extraction (the extraction of lithium-containing salts from underground brine reservoirs, so-called salars), or ore mining (lithium-containing rock, such as spodumene).
There is an ample opportunity in lithium battery recycling when used batteries are reused into a new source of the battery-grade product.
Benefits of lithium processing by MEGA
Benefits of MEGA ED in lithium ore mining process
Purification of lithium carbonate from sulphate solutions has never been more effective since MEGA has patented its special electrodialysis.
Massive reduction of unit operation steps (technology complexity).
Double replacement reaction aided with selective ion-exchange membranes.
Achieved high Li2CO3 purity with SO42- < 100 mg/kg dry matter.
Electrodialysis lowers the amount of water-salt solutions for handling.
Electrodialysis is saving costs for the evaporation steps.
Benefits of MEGA ED for lithium battery recycling companies
Special ED by MEGA makes recycling efficient and sustainable to recover key materials from all types of lithium-ion batteries. The main benefits of using ED in the Li-ion battery recycling process are:
Reduction of the production complexity and waste management.
High purity commodity Li2CO3 product where SO42- < 0.05 % DMB.
Possibility of mother liquor recycling to the neutralization step.
It is possible to separate Li2CO3 from Na, K, and Rb salts species by precipitation following ED.
MEGA currently offers its electrodialysis units for installation in all lithium processing plants. This means lithium processing from brine, rock mining and battery recycling. The main use of our technology is in
Car batteries (electromobility)
Energy storage devices
