Accurate Dunite Mineral Analysis for Industrial and Geological Applications
At TCRC Group, we offer advanced dunite mineral analysis services tailored for industries where thermal resistance, chemical stability, and high magnesium content are essential. Our NABL-accredited testing methods help clients accurately assess the composition, performance potential, and industrial viability of dunite rock. From metallurgical processes to refractory lining and environmental remediation, the suitability of dunite depends heavily on the concentration of olivine mineral, its elemental purity, and its petrographic integrity.
What is Dunite?
A magnesium-rich ultramafic rock crucial for industrial metallurgy and refractory systems
Dunite formations represent olivine-dominated ultramafic rocks (≥90% volume) containing trace chromite, pyroxene, and spinel crystalline phases. Thanks to its rich magnesium oxide (MgO) content and excellent resistance to heat, dunite is widely utilized in steel manufacturing, slag modification, and the production of refractory materials. Understanding dunite composition is essential to determine its suitability for high-temperature industrial applications.
Our mineralogical testing includes:
- Olivine content quantification
- CaO, MgO, and SiO₂ percentage analysis
- Trace metal detection (Cr, Ni, Fe)
- Density, loss on ignition (LOI), and grain size analysis
Formation and Extraction of Dunite
From ultramafic mantle zones to industrial mineral hubs
Dunite forms in Earth’s upper mantle and is typically exposed in ophiolite complexes. Once extracted via open-cast mining, dunite requires geological and petrographic analysis to verify mineralogy and industrial feasibility. Testing during and post-extraction supports grade classification, purity validation, and material qualification.
Our lab supports this process with:
- Detailed dunite petrographic analysis under polarized light
- Advanced X-ray fluorescence and diffraction methods enable comprehensive mineral composition analysis
- Identification of associated minerals and potential impurities

Why Dunite Analysis is Essential
Accurate dunite mineral analysis ensures operational reliability and material compliance. Industries risk process inefficiencies or refractory failure when MgO content is substandard or contaminant levels exceed tolerances.
With our testing, you can:
- Verify MgO levels for metallurgical suitability
- Detect harmful trace metals (Cr, Ni, As)
- Classify dunite grades for specific industrial applications
- Meet internal quality benchmarks and regulatory expectations
