INCAMineral

INCAMineral is a powerful, automated, Mineral Liberation Analysis solution. It enables ore characterisation, provides vital data on metal recovery and enables process yield characterisation using multipurpose SEMs.

Exploiting the performance of Oxford Instruments’ large area SDDs (Ultim Max), it provides accurate classification of minerals at speeds comparable to dedicated systems – but with the flexibility to perform other investigations as required.

INCAMineral is a powerful, automated, Mineral Liberation Analysis solution. It enables ore characterisation, provides vital data on metal recovery and enables process yield characterisation using multipurpose SEMs.

Exploiting the performance of Oxford Instruments’ large area SDDs (X-MaxN), it provides accurate classification of minerals at speeds comparable to dedicated systems – but with the flexibility to perform other investigations as required.

Automated mineral characterisation

  • Reporting modal mineralogy
  • Liberation yields
  • Mineral locking and association
  • Particle and grain size distribution

Applications

  • Precious metal recovery (PGM)
  • Base metal recovery
  • Iron ore characterisation
  • Coal (mineral impurity analysis)

Performance

  • High speed acquisition using SDD technology
  • Automated analysis over wide area, resolution at the nanoscale
  • Based on proven Oxford Instruments algorithms


Flexibility

  • Works with most SEMs
  • Can be retrofitted to existing systems
  • Grain relocation for more detailed analysis using WDS, EBSD and complementary EDS techniques
  • Upgrade paths include large area mapping, quantitative EDS mapping and more

INCAMineral automatically analyses grains over a large area of the sample, typically several square centimetres.

Because of the resolution achieved, information on individual grains is available from the same acquisition.

  • Samples can be either grain mounts or polished sections
  • Particles, and the grains within them, are detected using the atomic number contrast derived from a backscattered electron image
  • A combination of X-ray data, morphological data from the BSE image is used to identify the minerals
  • Both morphological and phase information in each grain is stored in a database from which it can be retrieved and re analysed in greater detail at any time
  • Phase identification can be made by X-ray spectrum matching, but, even better, by real-time full quantitative analysis during the acquisition. This delivers the accuracy needed to distinguish chemically similar phases
  • The relationship between the individual grains and the parent particles is maintained for further post-processing
  • The post-processing module provides direct and convenient access to the data via a graphical user interface
  • Information is provided for individual grains as well as statistical information over the whole sample: mineral abundance, mineral associations, liberation and locking, grain size distributions as well as cumulative liberation yield graphs

Mineral Liberation Analysis using INCAMineral

Mineral liberation is a critical stage in the production of high quality mineralogical concentrates from their ores. The products(concentrates) must be of a suitable degree of purity for the downstream processes in which they will be used.
