Drenajes acidos de mina y posibles sistemas de tratamiento

Abstract

The main objective of this work is to analyze the treatment options available for acid mine drainage due to the fact that it is one of the inconveniences caused by the mining activity. Acid mine drainage is an effluent in which various sulfur minerals are oxidized, producing sulfuric acid. To find out the possible treatment systems, a documentary review was carried out. The physicochemical parameters obtained through bibliographic references were pH, temperature, electrical conductivity, dissolved oxygen and metals (Al, Fe, Cd, Mn, Se, Pb). The adequate system to treat the acid mine drainage generated in the upper part of El Oro was the system of artificial wetlands, because it is an efficient method, easy to operate and its application is lower cost.
