Determining Mineral Composition From Assays
The determination of mineral composition is necessary in the mineral sands industry. Tiwest has developed a procedure for safe and convenient determination of the mineral composition using a magnetic separation followed by chemical analysis using X-ray fluorescence spectroscopy. This then requires the conversion of the elemental assays to mineral compositions. A project at the Julius Kruttschnitt Mineral Research Centre has developed a convenient analysis method for this conversion. This analysis is based on a reconciliation of the of the assays of the sample with the standard mineral assays by making minimal adjustments based on the assay accuracies to both sets of assays. As well as providing the mineral composition it to be tested for other applications and variations of the procedure to be evaluated. Given a range of samples, testing for the accuracy of the assays of the standard minerals, has been demonstrated.
