Mining is the first step in the dirty life cycle of coal. When coal mines move in, whole communities are forced off their land by expanding mines, coal fires, subsidence, and overused and contaminated water supplies. Mines are quick to dig up and destroy forests and soils. But once the coal is gone, the problems they leave behind, like acid mine drainage, can persist for decades.
Biotechnology has mostly been applied to the extraction step, but also has contributions to make to the mining, size-reduction and separation/purification/recovery steps. Biotechnology also has the potential for playing an increasing future role in the treatment of the effluents of minerals processing plants and of metals-bearing wastes.
