ABSTRACT
A highly sensitive emission spectrographic method for the quantitative determination of trace elements in zinc sulphide minerals has been developed. Double-arc furnace electrodes and high-intensity interrupted current were used. Silver iodide was selected as a carrier. Detection limits of analysed elements proved to be low and reproducibility adequate.
