Geochemistry Guide 2026

Iron ore Lithium borate fusion and WD XRF analysis is the industry method of choice for the analysis of oxide iron ores. Single or multi-temperature LOI is available, customizable as required. Borate Fusion ranges are available to accommodate ore grade, process control grade and commercial analysis. High Magnetite containing iron ore will require oxidizing fusion (XRF76).

Graphitic carbon Our capabilities complement the mining lifecycle from exploration to production with targeted analysis.

This method can be analyzed to party or umpire quality standards (GT).

The Satmagan test provides a measure of magnetic susceptibility on pulp samples, with results expressed as magnetic iron. The Davis Tube test, separates various magnetic mineral phases from non-magnetic components on a range of size fractions of crushed iron ore at various stages of mineral processing. This allows for mass and elemental balancing.
