2. Gold Extraction Method From Silicate Inclusions. 3. Comprehensive Gold Extraction Method. To Wrap Up. After roasting-cyanidation process, most of the gold in the tailings is embedded in the iron oxide inclusions and silicate (quartz) inclusions.

This study presents the novel idea of a cyanide-free leaching method, i.e., glycine-ammonia leaching in the presence of permanganate, to treat a low-grade and copper-bearing gold tailing. Ammonia played a key role as a pH modifier, lixiviant and potential catalyst (as cupric ammine) in this study. Replacing ammonia with other pH modifiers (i.e., sodium hydroxide or lime) made the extractions ...
