Researchers Develop Low-Temperature Method to Convert Lithium Hardrock into Battery-Grade Lithium Carbonate, Silica and Alumina
A new study describes a process that converts lithium hardrock into battery-grade lithium carbonate, cementitious silica, and smelter-grade alumina at temperatures below 100°C.
themarketherald.com.auResearchers reported a sustainable way to convert lithium hardrock into battery-grade lithium carbonate, cementitious silica, and smelter-grade alumina at temperatures less than 100°C. The conversion produces three separate compounds from the same feedstock.
Cementitious silica is another. Smelter-grade alumina is the third. @ScienceMagazine reported the findings in a new study. The study presents the process as a low-carbon alternative to conventional hardrock refining.
The report notes that lithium demand is rising and that the carbon footprint of current refining methods undercuts the sustainability goals the metal is intended to support.
