Sources. Lithium comes from two very different types of deposits. It is mined from pegmatite and recovered from the mineral spodumene, and to lesser extent, amblygonite, lepidolite and petalite, mainly from deposits in the USA, Canada and China. Lake brines and playa evaporites also contain lithium; USA and Chile are important sources.
