Rare Earth Elements: The Hidden Power Behind Modern Technology and Global Geopolitics

Introduction: Why Rare Earth Elements Matter

Rare earth elements (REEs) are the unsung heroes of modern technology. From the smartphone in your pocket to the jet engines that guard national skies, REEs are everywhere. Despite their name, these elements are not particularly “rare” in terms of abundance. Instead, their rarity lies in the economic, political, and technological complexities of mining, refining, and commercializing them.

In today’s rapidly evolving global economy, rare earth elements are more than just industrial commodities—they are strategic assets. Countries like China, India, the U.S., and Australia are competing to control supply chains, while industries ranging from defense and aerospace to semiconductors, automotive, and renewable energy depend heavily on these critical minerals.

This article takes a comprehensive look at rare earth elements—what they are, their history, their applications, and their role in geopolitics and business strategy.

History and Discovery

• Rare Earth Elements Discovery:
  The story began in 1787 when Swedish army officer Carl Axel Arrhenius discovered an unusual mineral in a quarry in Ytterby, Sweden. Over the next century, chemists identified new elements from this mineral, giving rise to the “rare earth” family.
• Rare Earth Elements History in Industry:
  Initially, REEs were curiosities in laboratories, but by the 20th century, they powered color televisions, nuclear fuel cycles, and advanced electronics.

Rare Earth Elements in India

India is home to significant deposits of monazite sands along its eastern coast (Odisha, Kerala, Andhra Pradesh, Tamil Nadu). While India holds 6% of the world’s rare earth elements deposits, it lags in large-scale processing and refining.

• Rare Earth Elements India – Current Scenario:
  • Managed largely by Indian Rare Earths Limited (IREL), a public sector enterprise.
  • India’s deposits are rich in cerium, lanthanum, and neodymium.
  • Applications include defense, nuclear energy, and renewable industries.
  • However, India still imports processed REEs from China due to limited refining capacity.

Global Distribution and Production

• Rare Earth Elements Countries & Deposits:
  • China: Controls 60–65% of global production and nearly 90% of refining.
  • USA: Mountain Pass mine in California.
  • Australia: Lynas Rare Earths, one of the few non-Chinese producers.
  • India, Brazil, Vietnam, Russia: Significant reserves but underdeveloped supply chains.
• Rare Earth Elements Deposits by Country (2024 estimates):
  • China – 44 million metric tons
  • Vietnam – 22 million metric tons
  • Brazil – 21 million metric tons
  • Russia – 12 million metric tons
  • India – 6.9 million metric tons
• Rare Earth Elements Cost:
  Prices vary widely. Neodymium oxide costs $70,000 per ton, while cerium oxide is far cheaper ($5,000 per ton). The cost is influenced by purity, demand, and strategic control.

Extraction, Processing, and Manufacturing

• Rare Earth Elements Extraction Process:
  Extracted primarily through open-pit mining, followed by chemical separation and refining. This is energy-intensive and environmentally challenging due to radioactive byproducts (thorium and uranium).
• Rare Earth Elements Processing Plants:
  China dominates, but plants are emerging in Australia, USA, and India to diversify global dependence.
• Rare Earth Elements Manufacturers & Exporters:
  • China Northern Rare Earth Group (China)
  • Lynas Rare Earths (Australia/Malaysia)
  • MP Materials (USA)
  • IREL (India)
