Analytical Services

Mintek’s Analytical Services Division (ASD) is a well-established inorganic analytical chemistry laboratory that specialises in geochemical and metallurgical analyses. We provide this specialised analytical service to the mineral, metallurgical and related industries, using state-of-the-art instrumentation for a variety of techniques.


Mintek is one of South African producers of Metallurgical and Geological Certified Reference Materials or “SARMS”. These materials are made according to ISO Guides 30 to 35, which describe the best practices for Manufacturing and Certification. There are over 100 reference materials available (ores, heavy minerals, soils, sediments, coal and rocks). There is a continuing program to increase the number of reference materials available. These materials are intended for use as controls in the analysis of similar samples, for verification of analytical methods, and for the calibration of equipment used for analyzing similar materials.

All the materials in the SARM series are manufactured and certified according to modern best practice. Particular care is taken to ensure the usability of the material, and to calculate a realistic assessment of the inter-laboratory uncertainty values. Each material is issued with a certificate that sets out the certified values and their standard deviation. Details of the preparation and analysis of the material, a list of the collaborating laboratories, a statistical analysis of the data, and instructions for using the material are also included.

Mintek has to date produced and certified more than 110 SARMs, comprising a wide variety of ores, alloys, and geological materials. In addition to the SARMs, reference materials can be supplied to standards specified by clients. These materials are manufactured to the same rigorous standards as the SARMs, but to speed up production the analyses are conducted by selected commercial laboratories that have featured well in previous inter-laboratory studies.
