Mineral and Phase Analysis

Mineral and Phase Analysis

Mineralogical analysis is the study of materials to determine mineral composition and mineral structure. This analysis can be used to identify mineral species and understand their characteristics and properties.
Our skilled and experienced experts utilise a broad range of techniques for mineralogical evaluation, the primary techniques include:
• X-Ray Powder Diffraction – identification of mineral phases and quantification in bulk samples
• Scanning Electron Microscopy (SEM) with associated Energy dispersive X-ray spectroscopy (EDS)
• optical microscopy and petrographic analysis

Data interpretation is critical to mineralogical analysis; having the best team of operatives with the most appropriate instrumentation is essential.The microstructure, grain size, morphology and bonding or reaction structures can be evaluated through SEM and optical microscopy. With energy dispersive analysis (EDS), spatially specific elemental compositions can be determined. Petrographic examinations are used to establish the nature and structure of materials and are widely used for rock and mineral samples as well as cements and concretes.

Typical Technique Applications:
• Industrial minerals, ceramics, rocks and ores
• Fillers for polymers
• Crystalline silica for occupational hygiene
• Quality control of raw materials
• Identification of unknown or deleterious components
• Coated products
• Corrosion products and corroded materials

Analyses are often complimentary to other analytical techniques such as chemical, XRF or thermal anlaysis.
