5. Conclusions
It has been shown that the EDXRD method can be applied to
quantitative phase analysis of samples containing mixtures of
different minerals. Analysis of 20 samples containing six minerals
using a simple linear regression model shows that the mineral
components of the samples can be quantified to an accuracy of
better than 1 wt% despite the fact that most diffraction peaks
exhibit a high degree of overlap with other peaks. Further
investigation into more advanced data analysis models should
see a further increase in the analysis accuracy.
