These minerals are challenging to process because a single stone extracted from the earth can contain a mix of different types of minerals. Additionally, only a few countries are abundant in them.
China currently controls nearly 80% of the global market for processing rare earth minerals. Globally, there are approximately 130 million tons of these minerals. China holds over 44 million tons, Vietnam possesses 22 million tons, Brazil has 21 million tons, and Russia controls 12 million tons. The United States, in comparison, has about 1.2 million tons.
For the U.S., securing rare earth minerals is crucial for maintaining its position as a global superpower. These minerals are essential to its technological leadership, supporting everything from electric vehicles to 5G internet, and reducing reliance.
To illustrate the importance, Apple, one of America's leading tech companies, has announced it will invest $500 million in mining and processing these minerals within the United States.
The U.S. also aims to capitalize on Ukraine's vast mineral wealth, which is valued at an estimated $14 trillion. It's reported that the U.S. plans to replace its dependence on Chinese rare earth minerals with those sourced from Ukraine, given that the country is rich in these resources.
The minerals in question include Bastnaesite, Monazite, Xenotime, Allanite, Eudialyte, Loparite, Gadolinite, Cerite, Samarskite, Fergusonite, Parisite, Fluorite, and others.
These minerals are processed into valuable metals like Lanthanum, Cerium, Praseodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Lutetium, Scandium, and Yttrium. These are used in various industries, such as electronics, energy production, and medical technologies.
The cost of these minerals can vary significantly. For example, a ton of Cerium may cost between $2,000 and $4,000, while the price of Dysprosium can range from $300,000 to $500,000 per ton. The most expensive mineral is Terbium, which can cost up to $1.5 million per ton.
Rwanda's rich potential in rare earth minerals
Rwanda is one of the countries actively developing research in rare earth minerals through advanced technologies. History shows that these minerals have been mined in the country, and their presence continues to be significant today.
Jean Claude Ngaruye, Mining Exploration Division Manager at the Rwanda Mines, Petroleum and Gas Board (RMB), has told IGIHE that Rwanda has abundant reserves of these minerals.
"These minerals were mined before and after independence. Three types were particularly extracted: Monazite, Zircon, and Xenotime. These minerals are in high demand due to their use in modern technology, with Zircon also being utilized in the nuclear industry."
The regions with the most significant mining activity are located in Rwanda's Southern Province. These include areas like Rukarara in Nyamagabe, Nshili in Nyaruguru, and near Munanira rock.
According to Ngaruye, "These sites were part of the former Butare, with one area located in the Gishamvu sector of Huye District."
Minerals are also found in Musebeya, a region that stretches across Karongi, Nyamagabe, and Nyamasheke.
Monazite, for example, yields metals like Cerium, Lanthanum, Neodymium, Praseodymium, and Samarium, which are essential for producing batteries, audio systems, aircraft engines, and other high-tech devices.
These minerals are highly valuable. For instance, Neodymium is priced at about $70,500 per ton, while Praseodymium costs around $71,350 per ton.
Ngaruye pointed out that the reason these minerals are in such high demand is not due to their low cost but because of their crucial role in technological development and environmental protection.
"Mining is like any other business. When something is in high demand, prices rise. If supply exceeds demand, prices drop. [...] The prices of rare earths have decreased, which has led to our reduced interest. You wouldn't go looking for an unnecessary stone in the market. The reason America is pursuing them so aggressively is to build its own large stockpile and compete with China," he said.
Despite Rwanda's wealth of these minerals, Ngaruye observed that the country does not yet have a large-scale market for them. However, he believes there is potential for specific buyers to access these minerals.
"They were present. Although most of the mining has been done in the Southern Province, there are also signs of these minerals in other regions like Rulindo, Gatumba in Ngororero, and other areas. Research could be easy if anyone is interested."
Rwanda's mining growth
Although Rwanda is rich in rare earth minerals, processing these minerals, particularly Monazite, presents challenges. Monazite often contains Uranium and Thorium, which require advanced processing methods and significant investment.
Rwanda's revenue from mineral exports has seen steady growth, rising from $373 million in 2017 to $1.7 billion in 2024.
The country has set a target of reaching $2.2 billion in mineral production by 2029. This goal includes increasing the processing rate of extracted minerals from 40% to 80%. To achieve this, research will be conducted to identify new mineral-rich areas.
As of May 2025, the RMB has identified over 27,000 new hectares of land with significant mineral deposits.
