The micro-analysis of geological samples is common practice and provides valuable information on a variety of scales, for example in mineral exploration and process mineralogy. The exploration process and subsequent metallurgical understanding occurs on scales that vary by numerous orders of magnitude. An important link in this chain is the transition from samples collected in the field to analysis in the laboratory. The micro-XRF bridges these challenging scales of observations allowing micro-analytical interpretations to be easily related to field samples (i.e. visually), as well as enabling the ability to select appropriate samples for more detailed micro-analysis, which is often costly and time-consuming.
In this webinar we will present examples of the characterisation of cobalt-rich samples using a geometallurgical approach that employs geo-analytical techniques to achieve multi-scale, multi-modal, and multi-dimensional information. The focus of this study is on the analysis of drill core sections and their interpretation, from both an up-scaling and down-scaling viewpoint using micro-XRF as a key component of the overall workflow. The end result is a new perspective on commercial mineralogy incorporating details about liberation of both ore and gangue minerals.
