MIT researchers develop low-cost technique to extract lithium from hard rock (news.mit.edu)

• Low-temperature extraction from spodumene
• Closed-loop process with zero waste
• Spinout Rock Zero commercializing the technology

"MIT researchers have developed a low-temperature process to extract battery-grade lithium from the common mineral spodumene. The closed-loop method is half the cost of traditional extraction and produces no waste. It could enable domestic lithium production in the U.S. and reduce reliance on Chinese refineries."
