| Popis: | This paper presents the latest results from gold panning which was performed along the creek Meckin Dol. Research showed that the size of the tested gold aggregates ranges from 30 microns to about 600 microns, and the most frequently present form of gold aggregates was isometric - irregular form. The chemical composition of gold aggregates shows heterogeneity with an average gold content ranging from 74.15% - 99.32%, followed by silver with an average content of 0.3% - 24.68%,and an average copper content of 0.04 to 11.06%. Other impurities such as Fe, Bi, Se, and Te are represented with content less than 1%. In general it can be said that the examined gold aggregates, by their chemical composition, are characterized by high purity ranging from 750 to 996. |
