historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re ...
Yes, that number would need to be offset against the capital cost of new equipment if required, higher processing costs etc. but, given that average ore grades are declining and operating costs are rising, there are now some cases where the reprocessing of tailings works out cheaper than processing material.
