Rare Earth Minerals Demand

Rare earth minerals or Rare Earth Elements (REE) have emerged as a cornerstone of progress in the present web of geopolitics, sustainability, and technology. These minerals are now more in demand than ever but are often overshadowed by a few commonly recognized resources like gold and oil. REEs are a group of 17 chemically similar elements found on the periodic table. These include the 15 lanthanides, along with scandium and yttrium.

Despite their name, these elements are not specifically rare in terms of abundance. They are, however, often dispersed in low concentrations, thereby making economically viable extraction challenging. A few REEs have unique electronic and magnetic properties, making these indispensable in various applications, including consumer electronics and green energy technologies.

Ongoing Innovations in Technology to Augment Demand for REEs

Modern technology heavily relies on rare earth minerals as they are integral to the production of various gadgets and equipment. Components like speakers, vibrators, and screens use REEs for enhanced performance. According to a study, over 5.4 billion people worldwide use mobile devices, driving significant demand for rare earth elements.

Neodymium and dysprosium are key to manufacturing high-strength permanent magnets used in turbine generators. The Global Wind Energy Council reported that global wind capacity increased by 93 GW in 2022, amplifying the requirement for REEs.

Motors in EVs rely on rare earth magnets for their efficiency and durability. The International Energy Agency (IEA) estimated that Electric Vehicle (EV) sales surpassed 10 million units in 2022, with each EV containing about 2.5 kg of rare earth materials.

MRI machines and other diagnostic tools heavily rely on rare earth elements for precision and reliability. As the global appetite for cutting-edge technology grows, so does the demand for critical materials like rare earth minerals.

The push toward renewable energy sources have significantly increased the need for rare earth minerals. For instance, the International Energy Agency (IEA) predicts that achieving global climate goals could increase demand for REEs by up to sevenfold by 2040, thereby extending the rare earth elements market in the coming two decades.

Developments in Exploration, Extraction, and Recycling to Act as Emerging Trends

Countries like the U.S., Australia, and Canada are heavily investing in developing their rare earth reserves to decrease their dependence on China’s supply. For instance,

• Australia’s Lynas Rare Earths, one of the leading producers outside China, increased its output by 16% in 2022 to meet growing global demand for REEs.
• The U.S. has also reportedly invested US$ 30 Mn in the Mountain Pass Mine in California, which accounted for 15% of global rare earth production in 2021.

Recycling rare earth elements from end-of-life products is increasingly gaining traction. According to a study by the European Commission (EU), recycling could supply up to 25% of Europe’s rare earth needs by 2030. Companies like Urban Mining Co. are developing techniques to recover neodymium and dysprosium from used magnets, thereby decreasing waste and production costs.

Researchers are progressively exploring alternative materials to decrease reliance on rare earths. For instance, developments in ferrite permanent magnet technology have made them a feasible substitute for neodymium-based magnets in certain applications.

Innovations like bio-mining and solvent extraction are enhancing efficiency and sustainability of rare earth production. Bio-mining, which uses microorganisms to extract metals, has shown promise in decreasing environmental impact.

• A 2023 pilot project in Sweden demonstrated a 20% cost reduction compared to traditional methods.

Companies like Energy Fuels are leveraging novel solvent extraction technologies to refine rare earths more sustainably, contributing to the diversification of supply chains.

Dominance of a Single Country in Supply Chain Results in Geopolitical Concerns

China’s control over 70% of global rare earth production and 85% of processing capabilities makes other nations heavily reliant on exports from the country. For instance,

• In 2020, the U.S. imported 80% of its rare earth elements from China, highlighting a significant vulnerability in supply chains.

The U.S.-China trade war in 2019 underscored the strategic importance of rare earths. In 2019, China threatened to curtail rare earth exports to the U.S., leading to concerns about supply disruptions. These actions have prompted other countries to seek alternative sources and diversify their supply chains.

In response to geopolitical risks, several countries have initiated stockpiling programs. The U.S., for example, has established a strategic reserve of rare earth elements as part of its broader strategy to decrease dependence on foreign sources. Similarly, Japan’s Ministry of Economy, Trade, and Industry has made heavy investments in securing long-term rare earth supplies.

Countries are constantly collaborating to counterbalance China’s dominance. The Quadrilateral Security Dialogue (Quad), comprising the U.S., India, Japan, and Australia, has prioritized rare earth mineral cooperation. In 2021, the U.S. and Australia announced a partnership to develop new rare earth projects, including Australia’s Lynas Rare Earths facility in Texas.

Geopolitical tensions have further caused fluctuations in the prices of rare earth minerals. For example, between 2010 and 2011, the price of neodymium oxide surged by 750% after China imposed export restrictions. This price volatility has spurred countries and companies to invest in domestic production and alternative sources.

Diversification of Supply Chains is Crucial for Future Growth

Rising production beyond China is vital to decrease geopolitical risks. Development on REE deposits in Africa, South America, and Australia are predicted to open new export opportunities, thereby spurring growth.

The implementation of eco-friendly extraction and processing techniques is estimated to mitigate the adverse impacts of rare earth mining. Government authorities are anticipated to create policies to encourage investments in rare earth production and recycling while ensuring environmental safeguards. Continuous investments in rare earth alternatives along with innovative extraction methods are predicted to play a pivotal role in meeting future demand for REEs.
