A view of gold and other precious metal extractions from a new and wider angle, taking in both the earth and the metallurgical sciences. To name but a small number of the topics covered: – Occurrences of gold and silver minerals in their ores – Photomicrographs of refractory and amenable minerals/ores – The use of irregular gold and silver distributions for efficient planning of the extraction process – Microanalytical techniques – Descriptions of uranium and many base metals for comparison. Written with a broad audience in mind, from the manager of operations to the metallurgist, for the field geologist or other earth scientist, and for the professor and student alike.
