Abstract

The amount of kyanite in samples obtained from magnetic and density separations of a kyanite ore was established by a quantitative X-ray diffraction procedure employing an internal standard. The accuracy of the results at low kyanite levels was improved by adding pure kyanite to the samples, analyzing these mixtures and extrapolating back to the lower level. The results were verified by X-ray diffraction analyses of synthetic mixtures containing amounts of kyanite approximately equal to that indicated in the ore samples. The percentage of error is estimated to be ±3per cent of the amount present in the range of 20 to 80 per cent kyanite.
