Quantitative Analysis of Iron and Silicon Concentrations in Iron Ore …
The compactness (density) of the ore concentrate was found to have very little effect on pXRF readings. The pXRF readings for Fe and Si were comparative to laboratory-based XRF results. Based on the strong correlations between the pXRF and XRF results (Fe: R 2 > 0.99, Si: R 2 > 0.96), linear calibrations were adopted to improve the accuracy of ...
