Apr 25, 2018 · "The methodology selected is a function of the mineralogy of the ore. If the gold is associated with oxides, for example, it can be amenable to heap leaching. The grade also plays a key role. Heap leaching is used for lowgrade oxides, while highgrade ore (with or without oxides) is better suited to CIP or CIL methods," says Bundo.
