Digitalizing the Mining Industry - 3D Scanning of Core Trays to Produce Volumetric Bulk Densities

Geological drill core samples can be digitalized using the Minalyzer Core scanner. Data sets generated from this scanning include XRF geochemistry, high-resolution images, specific gravity, RQD, structural logging, and sample topography. While all these data sets are useful for geologists, the sample topography has been increasingly beneficial for the iron ore industry. These models can be used to derive the sample volume, making it possible to generate the bulk density of the a sample in a fast and automated way as an alternative to the Caliper method. The error is ranges between 0.01-0.025 g/cm3 depending on how competent or fractured the core is, making it a reliable and objective method.
