Testing and Evaluation

Our state of the art laboratories are designed to provide the fundamental testing and analysis of minerals including fillers and pigments, various metals, and hard materials.  Key processing and product development measures allow for complete in-house project development.  Mineral characterization, drill core testing, and final product application testing are all typical laboratory protocols. Typical ASTM standards and best practices are followed. We are glad to work with our clients to perform tests per their requested standards.

Rapid turnaround times of 24 to 48 hours are available on most tests.

• Abrasion
• Application Testing
• Bulk Density (Loose, Tapped)
• Brightness, Whiteness & L,a,b Color Values
• Calorimetry
• Chapelle, modified (metakaolin pozzolanic activity)
• Colorimetry
• Conductivity
• Crystalline Silica
• FTIR (Fourier Transform Infrared Spectrometer)
• Hegman Grind / Fineness of Grind
• ICP (Low level metals; Inductivity Coupled Plasma Mass Spectrometer)
• Loss on Ignition (LOI)
• Moisture
• pH
• Oil Absorption
• Opacity
• Particle Size & Distribution
  • Various Single Sieve Sizes
  • Sedigraph (to 1.5µm and <1.5µm)
  • Ro-Tap (dry) Roundness & Sphericity
• SEM (Scanning Electron Microscopy), TEM and EDAX
• Specific Gravity TGA / DTA
• Viscosity (Brookfield / High-Shear)
• X-Ray Diffraction (XRD)
• X-Ray Fluorescence (ED-XRF)

Core Testing is available and rapid results can be received within 4 days of drilling, if needed. For kaolin / bauxite or similar cores, typical testing includes pH, +325 residue, brightness and color values, particle size. For sands, typical testing includes % of clay, Ro-tap with 5 sieves for particle size, angularity / roundness, and LOI as needed.
