Ключевые слова:copper, noble metals, melting, gold, silver, electron microscopy, impurity.
In the article we are presenting the results of electron microscopy study of the samples of blister copper taken
from copper production. It was shown significant amount of noble metals – silver and gold. As a result, silver was found in the
range of 0.29-0.59%, gold – up to 0.66%. The methodof assay-gravimetric detection of gold and silver in samples of blister
copper is described.
