Abstract

The ability to assay levels of gold and other valuable metals in mineral ores and process materials is essential for exploration, resource definition, mine planning and process control. Gold has traditionally been analysed using chemical methods, notably fire assay, which are labour-intensive, time-consuming and involve the use of toxic or hazardous reagents. Chrysos Corporation is commercialising an alternative approach, PhotonAssay, that was originally developed by the CSIRO. Based on the principles of photon activation analysis, the method uses a high-power, high-energy X-ray source to excite nuclear changes in any gold atoms present in a sample, and then measures a characteristic signature emitted by these atoms. The process is non-destructive, rapid, highly specific and capable of providing a true-bulk analysis of samples weighing 500 g or more.
