Global gold mining company AngloGold Ashanti has installed energy regeneration and capture turbines in its underground mines to reduce the mines electricity expenditure.
Anglogold confirmed that it has reduced its dependency on the national grid by 20% in the past six years while collaborating with Eskom to decrease its power consumption during peak periods by moving its pumping and rock hoisting loads, Creamer media reported.
AngloGold Ashanti COO South Africa Mike O’Hare said “What we’ve done is put in energy regeneration and capture plants in the form of turbines at two of our mines”.
O’Hare said that should the mine be cut off from the national grid, the mine can rely on their own self generating emergency power equipment to leverage miners underground back to the surface.
Mines to invest in renewable energy
AngloGold Ashanti is also considering alternative sources of green energy to further boost its emergency generation capacity such as wind and solar farms.
In addition, South Africa’s largest producer of gold Sibanye Gold mine is developing a ZAR3 billion ($257 million) solar power farm to reduce its dependency on the national grid.
This solar farm is expected to generated 150MW of power which will be used to power the mines daily operations.
AngloGold Ashanti is headquartered in Newtown Johannesburg with 20 gold mining firms in 10 different countries. The gold company was formed in 2004 when AngloGold and Ashanti Goldfields Corporation entered into a merger.
