Abstract. Petrographic and microanalytical studies of gold in goldsilver telluride deposits show that it occurs as "visible gold" extracted by cyanidation, and as visible gold and "invisible gold" that are unamenable to cyanidation. Two goldbearing tellurides, calaverite and buckhornite, are considerably less amenable to cyanidation in comparison...
