Chrysos PhotonAssay® is targeted at companies working across the minerals value chain.

Assay providers
.

Chrysos PhotonAssay® provides a highly cost-effective alternative to conventional chemical assay, especially fire assay. With a throughput of at least 50,000 samples per month, Chrysos PhotonAssay® Max is a work-horse for high volume labs, delivering cost savings along with a safer working environment. Customers will appreciate the rapid turn-around and high accuracy and repeatability that arise from direct analysis of 500 g samples.

Miners and mineral processors

Designed for rapid on-site deployment and low-maintenance operation, Chrysos PhotonAssay® Mine provides real-time grade information to support mine planning and process monitoring. Fully automated analysis reduces staffing requirements, and the chemistry-free technology eliminates hazards associated with toxic reagents.

Exploration drilling
.

Chrysos PhotonAssay® Mobile provides accurate grade information in bulk samples irrespective of their physical form, meaning that a core section or drill-chip sample can be easily measured. Chrysos PhotonAssay® Mobile will provide the ability to measure gold and other elements in the field – no more waiting days or weeks for laboratory results to be returned.

Commodities

Chrysos PhotonAssay® will be launched in 2017, initially providing a gold analysis service. Silver and copper assay are scheduled to be added in late 2017, with additional commodities added thereafter. Please contact us for information about specific elements.

Gold

Chrysos PhotonAssay® is uniquely sensitive for gold, providing accurate analysis for concentrations ranging from percent levels to below 0.1 g/tonne (0.1 parts-per-million). Traditionally hard-to-measure materials such refractory ores, carbon-pulps and copper concentrates can be easily assayed. Solutions and slurries can be directly measured, with the total gold content reported.

Silver

Chrysos PhotonAssay® has excellent sensitivity for silver over the full range of commercially relevant concentrations. Polymetallic ores can be easily accommodated, with the grade of each metal reported separately.

Copper

Unlike conventional chemical assay methods for copper, Chrysos PhotonAssay® quickly and accurately reports total copper content independently of the physical or mineralogical form. With sensitivity over the full range of commercially important concentrations, Chrysos PhotonAssay® can be used across the mining and processing value chain.

Other metals

We will continue to expand the suite of commodities that can be measured using Chrysos PhotonAssay®. More than half of all naturally occurring elements are sensitive to the technique. Please contact us with enquiries about the application of Chrysos PhotonAssay® to specific elements or commodities.
