Extraction of Gold and Copper from Flotation Tailings …
4. Conclusions The present study investigated the extraction of gold and copper from gold sulfide flotation tailings using a cyanide-free leaching method, i.e., glycine-ammonia solution in the presence of permanganate. The characterization indicated that the tailings sample contained 1.11% copper, 10.10% iron and 2.1 ppm gold.
