Assay & Testing (Geochemistry, Labs, WSMD, etc)

At Cotecna, we use assays to help our clients determine the true quality and value of their metals and minerals. Our accredited laboratories and experts use commodity specific methodologies to measure the elements and impurities contained in different samples against pre-set parameters. 
Our global network of accredited laboratories are strategically located to support your activities from pit to port. We offer expert geochemical assay and testing services including:

1. Chemical Assay

• Fire Assay: A traditional and highly accurate method for determining precious metal content, such as gold and silver, in ores and concentrates.
• Spectroscopic Analysis: Utilizing techniques such as X-ray fluorescence (XRF), inductively coupled plasma (ICP), and atomic absorption spectroscopy (AAS) to analyse elemental composition.

2. Mineralogical Testing

• X-ray Diffraction (XRD): Identifying and quantifying minerals based on their crystal structure and composition.
• Scanning Electron Microscopy (SEM): Providing detailed images and analysis of mineral surfaces to study texture, composition, and morphology.

3. Physical Property Testing

• Density and Specific Gravity: Measuring the density and specific gravity of minerals to assess purity and composition.
• Hardness Testing: Determining the hardness of minerals using techniques such as the Mohs scale or Vickers hardness test.

4. Metallurgical Testing

• Tensile and Impact Testing: Evaluating the mechanical properties of metals, including strength, ductility, and toughness.
• Corrosion Testing: Assessing the resistance of metals to corrosive environments and conditions.

5. Environmental and Geochemical Testing

• Soil and Water Analysis: Testing soil and water samples for mineral content and contamination to support environmental and geochemical studies.
• Acid-Base Accounting: Analysing mineral samples for their potential to generate acid mine drainage (AMD).

6. Custom Testing Solutions

• Tailored Assays: Developing and implementing custom assays to meet specific material and industry requirements.
• Consultation Services: Offering expert advice on assay methodologies, testing procedures, and data interpretation.

Our state-of-the-art testing facilities and experienced professionals guarantee accurate and reliable results, helping you achieve compliance and meet your contractual obligations.
