CSIR Mine Water Treatment Technology (VIDEO)
Published on by Dusko Balenovic, Previous Network Manager at The Water Network in Technology
The CSIR has developed and patented two wastewater technologies. One purifies mine wastewater to a standard that is suitable for domestic, agricultural and industrial use, while the other recovers valuable minerals from municipal wastewater.
Acid mine water is a by-product of the mining and mineral industry. Mines ceased pumping water as resources such as gold became depleted, resulting in water accumulating in the void and discharging into neighbouring mines and connecting underground tunnels.
Active and abandoned mines discharge millions of megalitres of metalliferous and acidic drainage, laden with toxic and hazardous chemicals per year, posing serious health risks to humans and other living organisms.

Recovery of water to a purity that allows use by the community is a boon for all. The recovery of mineral wealth from water has been done, even to the point of exploring recovery of gold from seawater (although I suspect the economics of that may not have "panned" out.) Obviously, the economics of such a plan depends on the volume of water to be "mined", the concentration of the resource in the water, and the ease of extraction of the resource. If all it involves is a simple ion exchange reaction, then it can be fairly economic, as long as the water can be further treated and used as a valued resource itself.
