Mill chemistry. The crushed and ground ore or the underground ore in the case of ISL mining is leached with sulfuric acid UO 3 2H UO 2 2 H 2 O UO 2 2 3SO 4 2- UO 2 SO 4 3 4-. The UO 2 is oxidised to UO 3.. With some ores carbonate leaching is cheap to form a soluble uranyl tricarbonate ion UO 2 CO 3 3 4-.This can then be precipitated with an alkali e.g. as sodium .

However due to the streamlining of operations and the construction of a 50km pipeline they have been re-engineered as milling and pump stations in support of the Ergo plant. Traditional recovery.

Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use underground mining where the ore is extracted through tunnels or shafts. South Africa has the worlds deepest hard rock gold mine up to 3900 metres 12800 ft underground.
The process to concentrate gold using cyanide was developed in Scotland in 1887 and was cheap almost immediately in the Witwatersrand gold fields of the Republic of South Africa. Heap leaching with cyanide was proposed by the U.S. Bureau of Mines in 1969 as a means of extracting gold from low-grade ores.

In 2003 a gravity gold recovery circuit was retrofitted at 1 Plant and each mill now has a 30-inch Knelson concentrator that recovers gold concentrate from the mill cyclone underflow. An Acacia intensive leach reactor is cheap to dissolve gold contained in the concentrate and this gold is then recovered from solution by electro winning.
Nevada was the birthplace of modern gold heap leaching in the late 1960s 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.
