Advances in Rare Earth Analysis and Their Relevance in the Modern Economy

The so-called Rare Earths, a group of 17 chemical elements, have become the backbone of several modern technology industries. Applications in electronics, renewable energy, defense and electric vehicles attest to their strategic importance. However, the accurate and efficient quantification of these elements is an ongoing challenge, mainly due to the complexity of their chemical and geological properties. In this article, we explore technological advances in analysing Rare Earth elements and how these advances influence the global economy.

The Rare Earth elements (Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sm, Tb, Th, Tm, U, Y, Yb) are indispensable in the manufacture of high-tech products, such as:

Permanent magnets: Used in electric vehicle motors and wind turbines.

● Electronic displays: Present in smartphones, televisions and computers.

● Industrial catalysts: Essential for oil refineries and emission control.

● Defence equipment: Including sensors, lasers and communication systems.

The growing demand for sustainable technologies, such as clean energy and electric mobility, puts Rare Earths in the spotlight. However, extracting and processing these elements requires precise analysis to ensure purity, efficiency and sustainability.

In recent years, advances in analytical methodologies have played a crucial role in optimising the exploration and use of Rare Earths. Some of the notable developments include ICP-MS, which is one of the most advanced tools for the detection and quantification of Rare Earths. It offers:

High sensitivity to identify minimum concentrations.

Accuracy and speed, reducing analysis time in industrial environments.

Applicability, capable of analyzing diverse samples, such as various types of ores.

This technique allows the qualitative and quantitative identification of Rare Earth elements in solid samples.

The application of advanced statistical methods in quality control ensures the reproducibility of results. Techniques such as multivariate analysis and uncertainty estimation are essential to validate results in large-scale projects.

Modern software integrates analytical data with geological information, allowing a more robust interpretation of the occurrence and distribution of rare earths in mineral deposits.

A few countries dominate the global production of rare earths, creating challenges of economic dependence. Advances in analytical methods are helping to identify new economically viable deposits in different regions, diversifying supply sources.

With more efficient analytical techniques, waste during extraction can be reduced, and recycling processes improved. This promotes a circular economy for rare earths.

Accurate analysis allows the development of more efficient materials, such as more powerful magnets and optimized catalysts, driving innovation in high-tech sectors.

With the demand for these elements constantly growing, the future points to the integration of even more advanced technologies, such as artificial intelligence and machine learning, in geochemical and mineral data analysis. These advances promise to accelerate the discovery of new deposits, optimize industrial processes and ensure the sustainability of the use of these strategic resources.

Rare Earths are essential to the modern economy, driving innovations in clean energy, electronics and defence. Advances in the analysis of these elements not only ensure greater efficiency in the extraction and use processes but also play a strategic role in the diversification of markets and the promotion of global sustainability. Such analytical advances, with the consequent achievement of more accurate analyses for the discovery and exploration of new deposits, would not be possible without certified reference materials (CRMs) containing rare earth elements, which are essential in QA/QC programs and in the calibration of analytical equipment, in addition to the monitoring of analyses such as those performed by ICP-MS.
