The determination of gold at 10−3–10−4% levels in black copper and speiss is based upon selective dissolution of the samples with sulphuric acid and separation of the matrix elements by filtration. Gold is determined in the solid residue by flame atomic absorption spectrometry. Relative standard deviation was 7%–10% for about 20 g Au/t.
