The direct procedure described uses a nitrous oxide-acetylene flame. Tests leading to its development are briefly described. The precision is approximately 1 per cent of the content over the ranges 4 to 63 per cent for lead, 5 to 21 per cent for copper, and 5 to 54 per cent for zinc. With the exception of zinc, for which there was a small negative bias, the values obtained agreed to within 5 per cent with those obtained by the method of standard additions, which, in the absence of suitable reference materials, was used for comparison.

The determination of minor elements in zinc, lead, and copper sulphide concentrates is described. The procedure involves the dissolution of the sulphide concentrate by fusion with sodium peroxide, acidification, with nitric acid, and measurement of the elements by atomic-absorption spectrophotometry. The method of standard additions is used to eliminate interference. The procedure is applicable to the analysis of ten elements at concentrations varying from 50 to 1000 ppm in the samples, with an accuracy of between 2 and 4 per cent.
