history
The Darlot Centenary Gold Mine is an underground mine . The deposit was discovered in 1996 and mining began by Homestake Mining Company in 1998. Originally the mine area was owned by Plutonic Resources , a major Australian mineral exploration company. Barrick Gold took over the mine from Homestake in 2008.
geology
The Derlot geological district is located at the southern end of the Yandal Greenstone Belt in the Yilgarn Craton . The deformed and metamorphosed volcanic rocks are deposited in tholeiitic basalts and in a doleritic reservoir. The corridor intrudes into granite on the eastern and southern borders of the district .
Mining operations and the environment
Barrick Gold also has this mine certified according to the International Cyanide Management Code and extracts the gold in a carbon-in-leach process. In this process, the rock is processed after crushing the rock, flotation and cyanide leaching with the help of activated carbon .
In the process of cyanide leaching, gold is chemically bound in highly toxic seepage water. After filtration and precipitation, brown sludge is produced which, after washing and drying, turns into raw gold through reduction . In this process, hydrogen cyanide and cyanides are produced , which can escape into the environment despite reuse of the lye. This can u. a. happen through accidents, leaks and disasters. All substances produced in this process are poisonous. Although these are easily decomposed and broken down in nature, the resulting large spoil heaps and cyanide dust can be distributed in an uncontrolled manner by wind and water, toxins can enter the environment in an uncontrolled manner and cause serious ecological damage.
