摘要

Diamond cores and drill chips provide the only direct physical evidence for ore containing rocks.rnEarly characterisation of cores and drill chips is important as it provides critical informationrnfor downstream processing. Traditional characterisation techniques include visual logging by arngeologist or analytic and spectroscopic methods but they are time consuming and can miss somernimportant textural or geomechanical features.rnThe goal of this work is to evaluate the application of image analysis to iron ore cores and drillrnchips and to suggest improvements to existing core-scanning and chip monitoring systems. Twornsamples of massive ore differing by their mineralogy and texture, as well as two different batchesrnof drill chips, have been imaged and analysed. Results are compared in function of the imagingrnsystem and the classifi cation algorithms.rnAs a conclusion, despite the necessity for more testing and improvements in calibration andrnlighting, it is obvious that image analysis technologies can bring a lot of useful information in thernperspective of a geometallurgical mapping of the deposit.
