The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silvertelluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4 ...
