Advanced Mineral Characterisation
Available advanced characterisation equipment allows the collection of high accuracy chemical and mineralogical information.
The Hylogger3 technology, developed by CSIRO, allows rapid acquisition of mineralogical information and high resolution images from drill cores, rocks chips, pulps and other materials. The mineralogical identification is performed through reflectance spectroscopy and its non-destructive nature makes possible to perform the analysis in original sample containers. This results in a high productivity, reaching a rate of analysis of 300 – 400 m of drill core per day, approximately.
Hyperspectral analysis characteristics:
- Reflectance spectroscopy in 400 – 2500 nm and 6000 – 14500 nm ranges, allowing the identification of sulfates, quartz, feldspars, carbonates, oxides and hydroxides, phyllosilicates and tourmaline, among others.
- High resolution images acquisition, associating each point to a spectral measurement.
- Minimal requirements of sample preparation: surface powder and residues removal. Drying of wet samples if necessary.
- Quick and non-destructive.
Rigaku Miniflex 600 - X ray diffraction (XRD)
The Rigaku MiniFlex600 is an X-ray diffraction (XRD) equipment used for qualitative and/or quantitative analysis of polycrystalline materials. It can be assembled with acopper or cobalt anode, the last being especially useful for phyllosilicates (clays) analysis.
Olympus Delta Premium - X Ray Fluorescence (XRF)
The Olympus Delta Premium is a portable X ray fluorescence (pXRF) equipment. It comes with a test stand for laboratory analysis of pulverized and/or liquid samples.
The equipment has a 40 kV tube which allows rapid chemical data acquisition. Its portable nature makes it suitable for on-site analysis of rocks, grounds, metallurgical samples, among others, working with multiple calibration models to ensure optimal performance for light elements as aluminum, silicon and magnesium.
Advanced characterization techniques allow to perform quality control works (QA/QC) from the obtained compositional information, such as:
- Review and adjustment of the information obtained through the use of appropriate standards.
- Characterization methods reliability asessment by crossing compositional information obtained with different techniques and experiments repetition.
