I just did a quick calculation on the Luanshya tailings, where they are doing the large scale testing, based on the gly-leach recovery of 80% copper.
There are 3 tailings dams but one is quite low grade so discarding that one for now, there are an estimated 103 million tonnes of tailings at 0.3% copper average: 103,000,000 x 0.3% x 80% = 247,000 tonnes of recoverable copper.
At Kitwe there are an estimated 114 million tonnes at 0.3% copper, so:
114,000,000 x 0.3% x 80% = 273,000 tonnes of recoverable copper
So a potential total of about 520,000 tonnes of recoverable copper.
