Lithium. Refined.
LiChem provides a patented lithium refining solution for participants in the lithium-ion battery value chain, at reduced costs and lower emissions, helping simplify the complex, inefficient and environmentally challenging lithium supply chain in place today.
LiChem controls the global patent portfolio for the Hunwick Process, a closed-loop lithium refining solution that has been in development since 2015 and is now moving to commercial development.
The key advantage of the Hunwick Process lies in the use of an alternative reagent compared to the conventional sulfuric acid roast and the Metso / Outotec alkaline high-pressure leach processes used in the lithium industry today. The alternative reagent allows for a closed-loop system through the recycling and re-use of the relevant reagent. As a result, significantly fewer reagents are consumed, less waste is produced, and fewer emissions are generated.
The Hunwick Process is expected to be applicable to various lithium feed sources.
The Hunwick Process’ closed-loop system is the only logical technology choice.

The Hunwick Process is well positioned to commercially refine spodumene concentrate and we believe is applicable to other sources of lithium, such as claystones and micas.
LiChem is willing to consider joint ventures and collaborative agreements to construct and operate lithium refining facilities using the Hunwick Process located near a partner’s mine, production plant or other strategically competitive locations.
We are willing to support partners in funding lithium mine development and expansions through direct equity investment.
Additionally, LiChem is open to sub-licensing the Hunwick Process technology in specific circumstances.
