The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation.
In the main, the beneficiation strategy is supported by a number provisions within existing national policy and legislation, such as the Minerals and Mining Policy for South Africa (1998), Minerals and Petroleum Resources Development Act, the Broad-Based Socio Economic
1.1.6 Beneficiation Although metallic ores contain elevated levels of metals, they generate large quantities of waste. For example, the copper content of a good grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is
