Integrated mine tailings management by combining
Calcium dissolution in the two tailings studied (Fig. 4c) is a response to sulphide oxidation, which promotes dissolution of neutralizing minerals (Ca-bearing minerals) to neutralize acidity produced by oxidation.

Tourists in Australia Flirt with Death in Asbestos Ghost Town
Mountains of tailings — the product left after asbestos is separated from the ore — containing around 150,000 tons of raw asbestos fibers were dumped and remain to this day. Numerous signs warning people to stay away have done little to prevent the hordes of travelers, including those with small children, from camping, hiking and swimming

How mine tailings could help in the fight against climate
The research could even help remediate the three million tonnes of deadly asbestos tailings in the gorges of Wittenoom. Mr Southam said it was possible the bacteria could break down Wittenoom’s asbestos piles, but it was unlikely to carry the same environmental benefit as other deposits.

Asbestos could be a powerful weapon against climate change
The main minerals in the tailings there are plagioclase feldspars, which hold magnesium and calcium in a tight chemical structure, making them less reactive than other types of mine waste.
