Abstract
Automatic scanning systems can be used to detect value minerals in polished sections. These instruments have now reached a maturity level for the actual analysis, but since they generate a lot of information, the bottleneck is now the interpretation of the data flow to get quantitative information. In this case, two methods, particle texture analysis (PTA) and QEMSCAN, are checked for differences. Measured properties were modal mineralogy, mineral associations and mineral liberations in several samples over the same size fraction 38–53 μm. The material is an apatite iron ore. The result shows the similarity between both methods. However, the modal mineralogy for one section in the concentrator looks almost identical for the two systems, while the modal mineralogy for another section is different in the estimation of gangue content.
