BN Aqua Acid Mine Drainage
Using a metallurgical waste product, the invention consists of a method to treat acidic water from mining sites. The treated water can be used for industrial application or with additional steps be treated for potable usage.
Water is currently a scarce resource in South Africa and the depletion rate threatens our water sources. Acid mine drainage, in particular, causes environmental damage long after mining operations have ended. The mines spend significant amounts of money to manage acid mine drainage and have also resorted to paying punitive fines for non-compliance to environmental regulations. An innovative water treatment solution is required to rehabilitate the environment through pollution remediation of the waste material and increasing potable water capacity.
By treating the acid mine drainage, mines can become less dependent on municipalities and reduce their drinking water as well as industrial water usage costs. This will increase the municipalities’ water capacity which will subsequently increase South Africa’s water footprint.
