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.

Treatment of Acid Mine Drainage using Magnesium Hydroxide

pH cannot be raised sufficiently. There are two mechanisms operating when metal containing acid water is neutralized with Mg(OH)2. The first mechanism is where metals are precipitated at metal hydroxides. The second mechanism is where metals are absorbed onto the surface of Mg(OH)2 particles. Teringo (1987) found that with Mg(OH)2, metals can

Sulfates in Wastewater Treatment | P2W - Pollution to Water

One of the processes that are causing high concentrations of Sulfates in water affected by mining is commonly referred to as Acid Mine Drainage (AMD) or Acid Rock Drainage (ARD), and is associated with the formation of acid water from Metal and Coal mines where pyrites are predominantly present.
