GOLD AND OTHER PRECIOUS METALS - OCCURRENCE, EXTRACTION, APPLICATIONS (additional information)
Some of the subjects addressed include:
- Gold and silver mineral occurrences in their ores, described to a detail never realized before.
- Refractory and amenable ores. Logical arguments, along with persuasive photomicrographs, prove how the occurrence and nature of the precious metal in the ore differentially affect the process of extraction.
- Incorrect approaches and common misconceptions that may directly affect the process of extraction.
- Differences between gold and silver and their effects on the process of extraction.
- The truth about fire assay. It may not always give the correct answer.
- Advantages and unique capabilities of the microanalytical techniques, when compared to the mineralogical observations, still used by most United States laboratories, for the study of the precious metal ores.
- Descriptions of uranium and many base metals for comparison. Compelling evidence why a different approach is needed for the study and planning of the precious metal ores.
