| Abstract: | A study of the impurity distributions in copper obtained from various ores shows no significant correlations between the impurity distributions. A test of 390 samples of copper obtained from various ores shows that more than 75% of copper samples can be correctly identified as coming from either simple copper metal ores, oxidized ores or more complex reduced ores thereby yielding information on the metallurgical capabilities of the society smelting the ores. |
