As seen above, the ,mine, water consists of a considerable amount of dissolved minerals which give rise to increase in water hardness. The pH indicated here is particularly for Illawarra region. In most of the other regions the pH ,can, be as low as 2 - 3 resulting in ,acid mine, drainage. This low pH is mainly due to oxidation of sulphides in coal.

Anaerobic biological treatment of ,acid mine, drainage from abandoned mines using SRB has shown nearly 99.2% effective removal of copper, zinc, and nickel (Sierra-Alvarez et al. 2006). The use of suspended biological methods for bioremediation of ,wastewater, and resources recovery is an eco-friendly and cost-efficient way.

This is equal to 140 tons ,acid, load per year. After the installation of the limestone drain the ,acid, load exiting the site was 192 mg/l which equals 42 tons ,acid, load per year, a 71% drop in ,acid, load. The limestone drain cost $10,000 to install and when considering the life of the limestone, the cost per ton of ,acid, load ,treated, is $34.

Based on the results obtained, it ,can, be concluded that four times less ,acid mine, drainage from the adit (1:0.24 v / v) should be used to neutralize the flotation ,wastewater, water to pH 7. It is also possible to reduce sulfate content from circa 10,000 to less than 2500 mg·L −1 ( Tables S1 and S3 ).

There are four chemical reactions that represent the chemistry of pyrite weathering to form ,acid mine, drainage. An overall summary reaction is as follows: 2 FeS2+7 O2+2 H2O → 2 FeSO4-+2 H2SO4 Pyrite + Oxygen + Water → Ferrous Sulfate + Sulfuric ,Acid,. The ,acid mine, drainage waste is characterized by red water. The simplest treatment is neutralization and clarification.
