Most beneficiation plants separate the valuable minerals from the waste minerals by physical means. Understanding the mineralogy is paramount for this activity. Understanding how the ore and gangue minerals behave in the metallurgical processing requires qualitative and quantitative knowledge of ore and waste minerals present and their textures and associations.
SGS Minerals has X-Ray Diffraction, electron microprobe microscopy, QEMSCAN®, image analysis and optical microscopy available to provide objective data. High definition mineralogy can be used for iron ore as it can examine a large amount of particles and can therefore provide statistically meaningful quantitative data. In addition, it produces digital data, which can be sorted using a computer program. For instance, it is possible to sort the particles by their specific gravity, based on the specific gravity of the minerals making up the grains. The advanced characterization available from the SGS network facilities provides the following advantages:
- Characterisation of raw materials
- Selection of suitable raw materials
- Comparison of different ore types
- Quality control of raw materials
- Identification of deleterious elements
- Monitoring of product consistency and quality
In addition to basic compositional analysis, SGS can provide comprehensive analytical overviews of mineralogical characteristics and their influence on metallurgical properties including:
- Reduction Disintegration Index (RDI)
- Tumble Index (TI)
- Reducibility Index (RI)
- Cold Strength
