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.

We assessed the co-treatment of ,acid mine, drainage (AMD) and OMWW using SRB-enriched bioreactors and identified the most abundant bacterial populations present under optimized conditions. The process requires a neutralizing agent to create optimal pH conditions for successful removal of the AMD’s main contaminants.

16/8/2015, · As pyrite-bearing mine wastes produce AMD in the presence of water and oxygen, one way to prevent AMD production is the exclusion of either one or both of them from the system. Co-disposal of pyritic materials along with some benign material (waste rock, limestone) is the most common practice to reduce AMD production from mine waste [ 16 – 18 ].
