some artisanal gold miners in South Africa, mainly in the Mpumalanga Province. Unfortunately the method is in widespread use in some African countries (Sudan, Tanzania, Congo, Zimbabwe), with devastating consequences for human health and the environment as mercury is released into rivers during processing (Global mercury Project, 2022).

In 1975, South Africa was responsible for producing 40% of the gold ever mined. By 2022, however, China affirmed its status as the world's largest gold producer with production of 324 tonnes of gold, followed by Australia ( tonnes), and South Africa with tonnes. Today, South Africa produces only % of the world's gold.

Stamp mills were used by miners in Samarkand as early as 973. They were used in medieval Persia to crush mineral the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. The basic design has not changed by much other than the drive mechanisms.

Mineral Processing. Since 1999 all ore has been sourced from open-pit mining operations and is currently processed at the Mtpa North heap leach facility and the Mtpa CIL plant. A third facility, the South heap leach facility was closed in December 2022. The ore is a free-milling conglomerate with negligible sulphide content. Weathering
