Mine tailings are the fine-grained material (clay sized to medium sand) that remains after the ore extraction process. The surface area of tailings impoundments can range in area from a few ha to several km and from 2 to 50 m in depth. The tailings are typically deposited into an impoundment as a slurry with up to 30 wt.% solids.

2 The process is initiated with pyrite oxidation and release of ferrous iron (Fe +2), sulfate (SO 4 2-), and hydrogen (H +) (eq. 1). The sulfur-oxidation process is accelerated by the presence of Thiobacillus and Ferroplasma bacteria. Ferrous iron undergoes oxidation forming ferric iron (Fe +3) (eq. 2).Finally, Fe is hydrolyzed (reacts with

The retreatment of tailings varies depending on the source of tailings and the material(s) to be recovered. The heap leaching and SX-EW processes have been key advancements in the ability to treat tailings; heap leaching, in which ore is agglomerated and stacked on a heap and then irrigated with a leachate, is ideal for low-grade ores.
