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.

Dump leaching. Heap and in-situ leaching characteristics are combined in dump leaching. Depending on the dump location, an impermeable layer may or may not be employed in a dump leach. The ore is dumped to allow similar processing to heap leaching, but the geological conditions of the area allow a valley or pit to act as the …

The Haib copper deposit is in the extreme south of Namibia close to the border with South Africa, which is defined by the course of the Orange River. The deposit lies some 12 –15km east of the main tarred interstate highway connecting South Africa and Namibia and the nearest railway station is at Grunau, some 120km north on the main highway.
