Acid mine drainages (AMD) are produced in the exploitation and mining production phase, where large quantities of water are required. Generally, they arise from rocks containing iron sulphides, such as pyrite and pyrrhotite, which, in contact with water and oxygen, react producing sulfuric acid and releasing metals such as Cu, Cd, Zn, Hg, Fe, Pb, y As. The AMD can negatively impact on the environment, since they can be dragged by the water sources near the mine, degrading the quality of water and land resources.This document shows a brief review of some of the antecedents of the mining industry, the environmental impact that generates and the different treatments used to minimize pollution by the manipulated waters in the process of the exploitation of the mining resources, promoting the implementation of bioreactors with reactive microbial mixtures or biomass. The interest to use biomass waste has two objectives: (i) to minimize the pollution and the environmental impact generated by the handled waters during and after the process of exploitation of the mining resources and (ii) To take advantage of agricultural waste.
