Improper disposal methods and the resulting environmental damages have plagued the history of the mining industry. These actions have left a negative stigma associated with mining and associated waste materials. For this reason, many countries now require miners to prepare a complete mine waste storage proposal before a mining permit will …

Driefontein is located in South Africa's West Wits Line goldfield, about 60km south west of Johannesburg. Driefontein Consolidated Ltd (Driefontein) was created in 1981 with the merger of the West Driefontein and East Driefontein mines. In January 1998, Gold Fields Ltd assumed management responsibility for the operation, which became a wholly ...
1 of 2. next ›. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in ...
Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa's Witwatersrand gold processing operations. According to Munyar Chirisa, a chemical engineer and senior manager of Deloitte, any tailings dump can be considered a potential mineral asset as …
