Industrial Minerals Testing
Clark Testing is an experienced analytical lab providing ASTM test methods for a wide range of Industrial Minerals Testing. Clark has a long history of providing analytical chemistry services for producers and manufacturers of industrial minerals. Our lab is operated under a rigorous ISO 17025 Quality Assurance Program which assures that testing meets our customer’s criteria for their application and industry specification.
Clark’s analytical chemistry laboratory is equipped with state of the art instruments to test and analyze a wide range of raw minerals. We routinely support testing for product validation and product comparison. In addition to chemical composition analysis we also provide particle characterization testing. Our particle characterization services provide particle size distribution, density, surface area, and porosimetry.
Clark provides ASTM sampling and sample preparation services either at mine sites or barge & rail transportation terminals. We have in-house sample prep capabilities with machining, grinding and polishing capabilities to ensure qualified test specimens are being analyzed.
Testing services most commonly include:
- Elemental analysis – As ,Fe, Mg, Al, etc.
- Elemental Oxides – Al2O3, SiO2, Fe2O3, etc.
- Pyritic Sulfur
