Profile
Rio Tinto is one of the world's largest mining companies, and its lithium business represents a significant move into battery-materials supply. Through acquisitions and projects, Rio Tinto has become a major prospective lithium producer.
The company's lithium activities include the Rincon brine project in Argentina and the proposed Jadar project in Serbia, and it substantially expanded its position through the acquisition of Arcadium Lithium, giving it lithium brine, hard-rock and lithium-chemicals operations and a customer base including major automakers.
Rio Tinto's scale and its lithium expansion position it to become one of the larger Western lithium suppliers to the battery industry.
