Low-grade carbonaceous gold ore from eastern Nevada was characterized by a variety of analytical and spectroscopic techniques with emphasis on vibrational spectroscopy. It was found that no detectable amounts of humic acid materials or organic hydrocarbons were present in the samples. Different hydrometallurgical techniques were used in an attempt to extract gold values from the carboneaceous ores. The techniques included the use of thiourea, diethylamine, and ammonium thiosulfate. None of these achieved the extraction levels gained by the standard hydrometallurgical practice of oxidation pretreatment followed by cyanidation. This report contains published papers covering most of the results of the study.
