Scientists are shaking up lithium extraction with a
The first time it is roasted at 1050°C (1976°F) to convert it to a state that is more suitable for chemical processing. In the second round, the mineral ore is cooked around 250°C (485°F) along with chemicals to form a water-soluble lithium compound. The resulting lithium product is higher quality than lithium extracted from brines.

Lithium is often obtained through open-pit mining, in which miners use explosives to blast holes in the ground that are then refined by heavy machinery into workable pits. The gathered spodumene (lithium-rich) ore is then trucked to a processing plant for the lithium to be extracted and refined through a labor-intensive, multi-step process.
