As gold production starts to fall, growing share of production will come from base metal mines
The supremacy of the stamp-mill for crushing gold and silver ores and the reason why for so many decades it so successfully withstood the attempts of both theoretical and practical men to supersede it or limit its application, lie mainly in its simplicity, reliability, and wide range of adaptability. The modern gravity-stamp has been evolved from the mortar and pestle used by primitive man ...
The quarterly gold output witnessed a 14 increase due to improved mill throughput. The remaining lower grade ore was stockpiled for processing in the years following the planned completion of mining in 2021. Under the current mine plan, stockpiles were forecast to peak at 137Mt in 2021, containing some 9Moz of gold.

Ore is treated using a two-stage crushing process, followed by a two-stage grinding circuit that consists of a semi-autogenous grinding mill and a ball mill. Most of the ground ore is fed to a gravity circuit that recovers about two-thirds of the gold, which is then smelted on site to form dor233 bars.
