Ore mined is processed at the Mponeng gold plant using conventional gold leaching methods carbon-in-pulp gold recovery technology.
Environmental Impacts of Gold Mining—With Special Reference to South Africa
Gold mining has serious negative environmental impacts, especially due to pollution emanating from tailings storage facilities (TSFs, tailings dams, slimes dams). The most important forms of pollution from TSFs are acid mine drainage (AMD) and high levels of potentially toxic elements (PTEs). AMD arises from the high levels of pyrite in the mining ores, …

How Does Gold Extraction Work?
Extracting gold is a multi-step process that can be approached in different ways depending on how a company is prospecting and mining its gold supply. For example, placer mining, which was popular during the 19 th-century gold rushes, relies on a gravity-separation extraction process. In these cases, water is used to separate gold particles ...
Gold Refinery Process: From Raw Material to Pure Gold
