The rare earth supply chain is a complex and critical system that plays a vital role in the production of many modern technologies. Rare earth elements are used in a wide range of applications, from smartphones and televisions to electric vehicles and wind turbines. However, despite their importance, the supply chain for these elements is often fragile and vulnerable to disruption.
One of the primary challenges facing the rare earth supply chain is the dominance of China in the production and processing of these elements. China currently produces over 80% of the world’s rare earths, giving them significant control over the global supply chain. This has raised concerns about the potential for supply disruptions, as well as the geopolitical implications of such a significant concentration of production within a single country.
As demand for rare earths continues to grow, it is becoming increasingly important to ensure the stability and resilience of the supply chain. This will require a concerted effort from governments, industry, and other stakeholders to diversify production and processing capabilities, as well as to develop new technologies and recycling methods to reduce reliance on primary sources of these critical elements.
Understanding Rare Earth Elements
Rare earth elements (REEs) are a group of 17 chemical elements that have unique physical and chemical properties. These elements are essential components of many modern technologies, including smartphones, electric vehicles, wind turbines, and defense systems.
REEs are not actually rare in the earth’s crust, but they are typically found in low concentrations and are difficult to extract. The majority of the world’s REEs are produced in China, which accounts for over 80% of global production.
The 17 REEs are divided into two groups: light rare earth elements (LREEs) and heavy rare earth elements (HREEs). LREEs include elements such as cerium, lanthanum, and neodymium, which are more abundant and easier to extract. HREEs include elements such as dysprosium, europium, and terbium, which are rarer and more difficult to extract.
The following table shows the 17 REEs, their atomic numbers, and their primary uses:

In conclusion, understanding the properties and uses of rare earth elements is essential to understanding the global supply chain for modern technologies. While China currently dominates the production of REEs, efforts are underway to diversify the supply chain and increase production in other countries.
Global Rare Earth Supply Chain
Mining and Extraction
The global supply chain for rare earths begins with mining and extraction. Rare earth elements (REEs) are found in various minerals, and their extraction requires extensive processing. China currently dominates the mining and extraction of REEs, accounting for more than 80% of global production. Other countries with significant REE deposits include Russia, the United States, Australia, and Canada.
Processing and Refining
After mining, REE-containing minerals undergo processing and refining to separate the individual elements. This process involves crushing, grinding, and chemical treatment to produce a concentrate rich in REEs. The concentrate is then further processed to separate the individual elements. China is also dominant in this stage of the supply chain, with most of the world’s REE processing and refining facilities located in the country.
Manufacturing and Production
Once the individual REEs have been extracted and refined, they are ready for use in various manufacturing and production processes. REEs are used in a wide range of products, including electronics, magnets, batteries, and catalysts. China is the largest producer of REE-based products, accounting for over 70% of global production. Other countries with significant REE manufacturing and production capabilities include Japan, South Korea, and the United States.
Overall, the global rare earth supply chain is heavily reliant on China, both for mining and extraction as well as processing and refining. However, efforts are underway to diversify the supply chain and reduce dependence on a single country. This includes increased exploration and development of REE deposits in other countries, as well as efforts to improve recycling and reuse of REEs.
Key Players in Rare Earth Supply Chain
China
China is the largest producer of rare earth elements, accounting for approximately 80% of global production. The country has a significant advantage in the industry due to its abundant reserves, low labor costs, and lax environmental regulations. The Chinese government also heavily subsidizes the rare earth industry, making it difficult for other countries to compete.
The leading Chinese companies in the rare earth supply chain include Baotou Steel Rare Earth, China Minmetals Corporation, and China Northern Rare Earth Group. These companies are responsible for mining, refining, and processing the raw materials before they are sold to manufacturers.
