Elemental and Metallographic Analysis of Metals, Minerals, and Metal-bearing Ores

Driving Progress from the Ground Up: Elemental Testing for Metals, Minerals & Ores

In the highly demanding world of metals and minerals, every detail matters. From the elemental makeup of raw ores to the precise composition of refined metals, obtaining fast, accurate, and reproducible data is essential for ensuring quality, efficiency, and meeting stringent compliance standards.

At LECO, we turn complex material analysis into clear, actionable results. Our advanced instrumentation and trusted technologies empower mining labs, steel mills, and foundries to optimize processes and validate materials across the entire lifecycle—from raw materials characterization to finished metal certification.

Get rid of guesswork with our line of metallographic instruments, built to adequately prepares your samples for in-depth, accurate analyses. 

Our sectioning machines, mounting presses, grinder/polishers, hardness testers, and metallographic microscopes enable clear visualization of grains, phases, inclusions, and defects, supporting quality control and process optimization across a wide range of materials.

We deliver precise determination of critical elements including Carbon, Sulfur, Oxygen, Nitrogen, and Hydrogen (C/S/O/N/H). Trust LECO’s flagship solutions—including our CS/ONH Analyzers (like the CS844 or ONH836), and Glow Discharge Spectrometers (GDS950)—for industry-leading reliability and compliance with ASTM and ISO standards.
