These data demonstrate the possibility of developed for the gold analysis in ores technique employment. Accuracy
of determination does not exceed 28%.
Determination of lead, nickel and cobalt in rocks from Altai-Sayan folded area was carried out without separation of
them from the sample matrix and with aqua sample digestion. After this we obtained results of analysis by two
methods: AAS with electrothermal atomization and the flame atomization (Table 4).
