China is one of the world's richest countries in terms of rare earth resources. Since the 1950s, the country has made significant progress in its rare earth industry. Through years of development, China has become the largest producer, user, and exporter of rare earth elements globally. However, while these valuable resources bring economic benefits, they also come with growing environmental and resource management challenges.
In an interview with a reporter from China Economics and Information Technology, Academician Xu Guangxian, often referred to as the "Father of Rare Earths," outlined several critical issues facing China’s rare earth sector. He emphasized the need to improve reserves, consolidate companies, address the Baotou tailings dam crisis, and enhance intellectual property protection. Additionally, he called for greater efforts in recycling rare earth materials.
The Baotou rare earth tailings dam is one of the most pressing concerns. As a non-renewable resource, rare earth elements must be carefully managed. Currently, the Main East Mine in Baotou is still being mined for iron, with only 10% of the rare earths being extracted, while 75% remain in the tailings. This massive waste has created an artificial lake covering 15 square kilometers—larger than the campuses of Peking University and Tsinghua University. The dam, which stands 35 meters high and grows by 0.9 meters annually, poses serious environmental risks. Pollutants could potentially seep into the Yellow River, threatening local ecosystems. To mitigate this, experts suggest draining the water, covering the site with soil, and restoring vegetation. If properly managed, the tailings could even become a new source of rare earths, helping to increase China’s share of global reserves back to around 33%.
Establishing a comprehensive rare earth reserve system is another priority. Countries like the U.S. and Japan have already implemented strategic reserves, securing their own supply chains. China, once supplying over 95% of the world’s rare earths between 1995 and 2005, now accounts for just 20% of global reserves. Despite having a production capacity of 150,000 tons annually, China’s exports exceed demand, leading to price volatility. In 2006, the government imposed production limits, causing prices to triple that year. However, after the 2008 financial crisis, prices dropped again, partly because foreign countries had stockpiled low-cost Chinese rare earths over the previous two decades.
Promoting the integration of rare earth companies is essential to avoid overproduction and inefficiency. China currently has numerous small-scale operators, unlike countries such as France, where only one rare earth separation plant exists. By forming two major national companies—one in the north and one in the south—China can better control supply and pricing. While an industry association has been established, it faces challenges in coordination due to its large membership. Only through consolidation and scale can China regain control over the market.
Recycling rare earth materials is also crucial. With increasing use in consumer electronics, energy-saving devices, and green technologies, China must invest in a robust recycling infrastructure. This includes recovering rare earths from spent batteries, fluorescent lamps, magnets, and industrial catalysts. A well-structured recycling system will not only reduce environmental impact but also extend the life of existing resources.
Combating illegal smuggling remains a challenge. Despite strict customs regulations, rare earths are still being smuggled out of China. Statistics show that foreign customs reported higher import volumes than what was officially exported, indicating a significant black market. Strengthening law enforcement and improving traceability are key steps to curb this issue.
Intellectual property protection is equally important. In the past, many scientists shared their research freely with state-owned enterprises, leading to technology leaks. Private and local companies then took advantage, luring engineers away and acquiring sensitive knowledge. Protecting innovations is vital to maintaining China’s competitive edge in rare earth technology and encouraging further R&D.
By addressing these challenges, China can transform its rare earth resources into a long-term economic advantage. Sustainable management, industry consolidation, and technological innovation are all necessary to ensure the responsible and profitable use of these critical materials.
