WebAcid mine drainage describes a natural process produced when the mining activities expose sulfur-bearing minerals (mostly iron sulfides) to atmospheric oxygen, moisture, and acidophilic iron-oxidizing bacteria, resulting in sulfuric acid, dissolved iron, and precipitation of ferric hydroxide. The chemistry of ANFO detonation is the reaction of ammonium nitrate with a long-chain alkane (CnH2n+2) to form nitrogen, carbon dioxide, and water. In an ideal stoichiometrically balanced reaction, ANFO is composed of about 94.5% AN and 5.5% FO by weight. In practice, a slight excess of fuel oil is added, as underdosing results in reduced performance while overdosing merely results in more post-blast fumes. When detonation conditions are optimal, the aforement…
