The well-understood processes of AMD formation have been reviewed in many scientific literatures (Lowson 1982; Kefeni et al. 2017; Naidu et al. 2019).Pyrite is initially oxidized by O 2, resulting in the release of Fe 2+, SO 4 2−, and H + (Eq. ())In the presence of atmospheric O 2, Fe 2+ is subsequently oxidized to Fe 3+ (Eq. ()), which significantly

2 · Dewatered tailings technology filters and extracts water from ore processing waste to produce a paste or bulk cake-like consistency. How much water can be removed depends on the type of tailings, but in a classic dewatered set-up, experts say volumes are expected to be reduced by around 30–40%. This water can then be reused in the

· Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today’s price, US$5,842/tonne, if that material could be reprocessed and an

· In mining areas, AMD formation becomes more extensive after mine closure because pumps used to keep the water table near open-pit and/or underground mines artificially low to facilitate mining activities are turned off, leading to the rise of groundwater level, which then reacts with exposed sulfide minerals on wall rocks (Soni et al.,

Pollution. In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore. Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
