In South Africa, the [[Witwatersrand Gold Rush]] in the [[South African Republic|Transvaal]] was important to that country's history, leading to the founding of [[Johannesburg]] and tensions between the [[Boer]]s and British settlers as well as the Chinese miners.<ref>{{Cite book |last=Ngai |first=Mae M. |url=https://www.worldcat.org/oclc/1196176649 |title=The Chinese question : the gold rushes and global politics |date=2021 |isbn=978-0-393-63416-7 |edition= |location=New York|oclc=1196176649}}</ref>

South African gold production went from zero in 1886 to 23% of the total world output in 1896. At the time of the South African rush, gold production benefited from the newly discovered techniques by Scottish chemists, [[Gold cyanidation|the MacArthur-Forrest process]], of using [[potassium cyanide]] to extract gold from low-grade ore.<ref name="MicheloudCrime">{{cite web |last=Micheloud |first=François |year=2004 |url=http://www.micheloud.com/FXM/MH/Crime/Gold.htm |title=The Crime of 1873: Gold Inflation this time |work=FX Micheloud Monetary History |publisher=François Micheloud: www.micheloud.com |url-status=dead |archive-url=https://web.archive.org/web/20060520104428/http://www.micheloud.com/FXM/MH/Crime/Gold.htm |archive-date=2006-05-20 }}</ref>
