1 February, 2024 Demand and supply. The best estimates currently available suggest that around 212,582 tonnes of gold has been mined throughout history, of which around two-thirds has been mined since 1950. And since gold is virtually indestructible, this means that almost all of this metal is still around in one form or another.

Gold cyanidation. Gold cyanidation (also known as the cyanide process or the MacArthur–Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. [1]

· The alarming increase in the proportion of gold miners with silicosis at autopsy reflects the failure of the mining companies to reduce silica dust to safe levels. There is no evidence to believe that silicosis levels have decreased since the 1940s ( 14 , 26 ), and this is supported by these findings.
