Heap Leaching - Metallurgist & Mineral Processing Engineer Nevada was the "birthplace" of modem gold heap leaching in the late 1960''s, and is only now giving up its dominance of this technology. Other very large gold districts – notably the pre-cambrian shield areas of Canada, Australia and South Africa – show relatively few heap leaches.
