Rio Tinto Accelerates Lithium, Copper Growth but Faces $20B Rare-Earth Risk
Rio Tinto has accelerated efforts to expand its lithium and copper portfolio for the energy transition but remains reliant on China-controlled rare earth processing. The rare-earth magnet market is valued at $20 billion and forecast to reach $30 billion by 2030, exposing Rio Tinto to downstream supply bottlenecks as Western processing scales to 600 tonnes annually by late 2028.
1. Expansion into Lithium and Copper
Rio Tinto has accelerated its acquisition and development of lithium and copper assets to support growing energy transition demand, targeting both upstream exploration and downstream integration into its existing mining operations.
2. Dependence on China-Controlled Processing
Despite this push, Rio Tinto remains exposed to China’s dominance over rare earth processing and magnet production, creating potential supply chain risks for electric vehicle and renewable energy markets.
3. Emerging Western Supply Alternatives
Non-Chinese processors are scaling capacity from 400 tonnes in 2027 to 600 tonnes by late 2028 to address the rare earth refining bottleneck, but Rio Tinto has yet to establish its own downstream processing infrastructure.
