A fundamental research on routine analysis by fluorescent X-ray method in the smelting of copper and nickel has been made. The sample used were ores, mattes and slags, while the elements determined were Cu, Ni, Co, Fe, Ca, S, Si, and Mg.<BR>Several representative samples from each lot were chosen to give standard samples, and those were analyzed accurately by the standard chemical methods.<BR>Calibration curves were made from the percentages of elements and their fluorescent X-ray intensities. Twenty nine combinations were obtained from the kinds of sample and the elements to be determined, and analytical conditions characteristic to each combination were given.<BR>The analytical error in each case was given by the variation in the difference of values obtained by fluorescent X-ray analysis and those by the standard chemical method. The standard deviations were 13% for the prime grade elements and 310% for most of low grade ones. The errors were comparable with, or even less than, those usually met in the rapid chemical analysis.
