The ability to delineate ore from waste in open pit mining operations is now in the palm of your hand. The XRF can be used directly in the bags collected from grade control drilling without any further preparation. Cuttings from blast holes can be analyzed directly at the surface of the hole or directly in collection bags without having to remove them for preparation. Having access to instantaneous data like this can save significant amounts of time that would otherwise be spent hauling samples to the laboratory. The ability to guide operations in real-time increases productivity which results in increased profitability. Numerous studies have been conducted proving that handheld XRF is an accurate, effective tool that can be used to monitor grade control with confidence.
In underground operations, the XRF can be used directly on the face. It is crucial to take multiple samples and average them in order to get a fair representation of a given area. Instantaneous data aides in predicting mill feed grades and blending high grade with low grade to ensure the mill operates at its highest level of efficiency. When differentiating grades becomes challenging, samples can be collected and prepared into a pulp for even more accurate results. A pulp is an ideal XRF sample as it is homogeneous in particle size.
