The use of micro organisms for heavy metal remediation in water is a technique widely studied. This review describes a number of methods used for Acid Mine Drainage (AMD) remediation, containing high concentration of this type of contaminant. The AMD is a problem generated in abandoned mines and low grade stock of active mines, therefore it is an existing problem in mining countries. In this review it is described the problem in Chile, regulations and the challenge to resolved this problem for a sustainable industrial future.
