The primary US rare earth mine is the Mountain Pass Mine in California, which plays a critical role in supplying materials used in electronics, robotics, and renewable technologies. For STEM learners, this mine provides a real-world example of how raw materials like neodymium and cerium are extracted and transformed into components such as motors, sensors, and circuit systems used in robotics kits and microcontroller projects.
What Is the US Rare Earth Mine?
The Mountain Pass facility, located in the Mojave Desert, is the only active large-scale rare earth mine in the United States as of 2026. Originally opened in 1952, it became globally significant in the 1960s when rare earth elements were discovered to be essential for color television screens and later for advanced electronics.
As of 2024 production reports, the mine contributes approximately 15% of global rare earth oxide output, with a focus on light rare earth elements like neodymium and praseodymium. These materials are essential for high-performance magnets used in robotics motors, drones, and electric vehicles.
Key Rare Earth Elements and STEM Applications
Rare earth elements extracted from the US mine directly connect to electronics education systems and robotics hardware commonly used in classrooms and maker spaces.
- Neodymium: Used in strong permanent magnets for DC motors and servos in robotics.
- Praseodymium: Enhances magnet strength and thermal stability in motors.
- Cerium: Used in polishing glass for optical sensors and screens.
- Lanthanum: Found in rechargeable batteries and camera lenses.
- Samarium: Used in high-temperature magnets and sensors.
How Rare Earth Mining Connects to Robotics Learning
Understanding the materials supply chain helps students connect abstract STEM concepts to real-world systems. When students build a robot using Arduino or ESP32, they are indirectly relying on mined rare earth elements.
For example, a simple robotics project involving a motor driver circuit uses neodymium magnets inside DC motors. These motors follow electrical principles such as Ohm's Law, where $$V = IR$$, linking mining resources to circuit behavior in practical builds.
Step-by-Step: From Mine to Microcontroller Project
The journey from raw material to a working STEM project can be broken into clear engineering stages.
- Extraction: Rare earth ores are mined from sites like Mountain Pass.
- Separation: Chemical processes isolate individual rare earth elements.
- Refinement: Materials are purified into usable oxides or metals.
- Manufacturing: Elements are turned into magnets, batteries, and components.
- Integration: Components are used in motors, sensors, and circuit boards.
- Application: Students use these parts in robotics and electronics projects.

Why Rare Earths Matter in STEM Education
Rare earth elements are foundational to modern electronics design, making them highly relevant for students learning robotics and embedded systems. Without these materials, many classroom tools-including sensors, microcontrollers, and communication modules-would not function efficiently.
Educators increasingly use this topic to teach interdisciplinary STEM concepts, combining chemistry (element separation), physics (magnetism), and engineering (circuit integration). This creates a deeper understanding of how real-world engineering systems are built from the ground up.
Classroom Activity Idea: Exploring Magnet Strength
Students can connect mining concepts to hands-on learning through a simple experiment involving magnetic field testing.
- Collect different magnets (neodymium vs ferrite).
- Measure lifting force using small weights.
- Record data and compare strength differences.
- Relate findings to motor efficiency in robotics.
- Discuss how rare earth materials improve performance.
Industry Insight
According to a 2023 U.S. Department of Energy briefing, "Rare earth materials are essential to over 90% of advanced energy technologies." This highlights the growing importance of domestic rare earth production not only for national security but also for STEM innovation pipelines.
