01 11 2015 A gold mine was under severe pressure because the gold grade of the ore body it was mining had fallen by around 20 percent The mine had increased ore production volumes to try to offset the decline but it was running into difficulties because this was overloading its leaching plant and incurring higher costs on energy chemicals and other major input costs.
Mines and gold mining operations have become increasingly geographically diverse far removed from the concentrated supply of four decades or so ago when the vast majority of the world s gold came from South Africa China was the largest gold producer in the world in 2016 accounting for around 14 of total annual production.
