In this report, we explore the application of PhotonAssay to the measurement of gold in real mineral samples sourced from Australian and international operations. In aggregate, nearly 12,000 measurements on approximately 2,000 separate materials have been performed. Click here to download your free copy.

This presentation reviews the application of Chrysos’ PhotonAssay technology in fields ranging from exploration to process monitoring, and grade-control to ore-sorting. It highlights results from recent studies on the measurement of challenging coarse gold deposits, and ongoing work to enable near real-time assays of process pulps without drying.

Precision refers to the repeatability of the measurement process – a precise analysis will consistently give the same result when tested on the same material. The term accuracy is used to refer to the deviation between the reported grade and the true value. An accurate analysis method is necessarily precise, but the reverse does not have to be true.

This presentation shows how Chrysos’ PhotonAssay solution provides rapid, accurate, safe and non-destructive ore grade analysis across the global mining industry.  PhotonAssay’s fast turnaround on high sample volumes delivers critical operational information and drives process opitimisation through the entire mining value chain.

PhotonAssay provides a unique, chemistry-free approach to material analysis. It hits samples with high-energy X-rays, causing short-lived excitation of atomic nuclei of targeted elements. These excited nuclei then give off a characteristic signature that can be detected and used to calculate metal grade. Click here to download your free copy.

This paper reports on the design, development, installation and commissioning of Chrysos’ first PhotonAssay system. Samples are packed into barcoded, screw-top plastic jars in which they remain throughout the analysis. Once loaded onto an input conveyor, the analysis process is fully automatic and requires no human intervention. Samples are returned unchanged and be safely disposed of or retained for future testing as required. Click here to download your free copy.
