Australia, the world’s leading producer, extracts lithium directly from hard rock mines, specifically the mineral spodumene.
Chile, along with Argentina, China, and other top producers, extracts lithium from brine.
Hard rock provides greater flexibility as lithium hosted in spodumene can be processed into either lithium hydroxide or lithium carbonate. It also offers faster processing and higher quality as spodumene typically contains higher lithium content.
Extracting lithium from brine, on the other hand, offers the advantage of lower production costs and a smaller impact on the environment. The following visual from Benchmark Minerals helps break down the carbon impact of different types of lithium extraction.
Note:
Reserves are not the same as Resources
Some ASX companies have Spodumene and Brine lithium resources
