Notes:
A method for rapid and accurate X-ray fluorescence analysis of a wide variety of slags from the copper producing industries has been developed. The samples are fused in a sodium tetraborate + lanthanum oxide flux with sodium nitrate added to ensure oxidizing conditions in the melt. Nine elements have been investigated, namely Cu, Zn, Fe, Si, Al, Pb, Sn, Ni and S. It has been found that simple linear calibrations give accurate results for most elements, but in the case of Cu, Zn, and Ni a correction procedure based on secondary mass absorption coefficients may sometimes be necessary.
