• Ginn-Mineral-Technology-Services

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.

Testing and Evaluation


Application Testing

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.

Mineral and Metal Processing

Our expertise in mineral processing is based on sound knowledge of the mineral composition from a geological perspective.  Ginn Mineral specializes in many forms of mineral processing as well as separation technologies such as magnetic separation, classification , and filtration technologies. We can perform processing on a lab scale up to a pilot plant and commercial scale.
