Summary
A new low-cost method for extracting lithium from hard-rock ores could reduce the energy, chemical intensity, and carbon emissions associated with traditional lithium mining. The technology aims to simplify lithium refining globally and could help lower dependence on China, which currently dominates lithium processing. The method cuts waste and emissions compared to conventional hard-rock extraction, which emits three times as much CO2 as extracting lithium from brines.
Key quotes
· 2 pulledMore than half of the world's lithium comes from minerals.
But wringing the critical battery metal from hard-rock ores is energy and chemically intensive and emits three times as much carbon dioxide as getting lithium from salty brines.
