GoldSouth Africa’s Witwatersrand Basin has been responsible for almost half of the gold mankind has ever produced, but more than a century of development has left the area with a dangerous legacy – dozens of spent mines containing vast quantities of acid. And while technology to deal with this is being developed, experts have been unable to suggest what the full cost may be.

In this webinar – aimed at anyone with an interest in environmental management, minerals, mining and sustainability – Craig Sheridan sets out the roots of Witwatersrand’s toxic threat and what South Africa is doing to combat it. He also looks at upcoming research that may help deal with the problem of acid mine drainage and how it can be applied elsewhere in the world.
