Abstract: Con el afán de contribuir en la remediación de una zona con efluentes acidas de minas, la investigación consiste en ensayos realizados en el Instituto de Minería y Medio Ambiente de la Universidad Nacional de Ingeniería, con el efluente donado por la minera Coricancha.
El objetivo de la presente es el fraccionamiento sistemático del efluente acido de la mina, la cual consiste en precipitar el hierro a un pH=5 con la adición de la lechada de cal, esperar la sedimentación para separar la fase liquida – solida; en la siguiente etapa llevar la fase liquida a un pH=10 con la adición del sulfuro de sodio, nuevamente esperar la sedimentación para la separación fase liquida – solida, para finalmente verificar si la fase liquida cumple con las normas D.S- 010-2010-MINAM y D.S. 015-2015-MINAM, para verter el agua resultante al cuerpo receptor o recircular en el sistema.
En cada etapa se obtuvo precipitados los cuales son denominados lodos, en la primera etapa de colores rojos pardos con un contenido de 21.7% de hierro aproximadamente, y en la segunda etapa de color blanco beige con un contenido de 23.8% de zinc. Los más abundantes son los sulfatos y cristales de yeso.
Luego se elaboró 4 briquetas de secciones pulidas de estos lodos, para realizar el estudio microscópico con el objeto de conocer su composición mineralógica. En una futura investigación se buscara el uso económico de estos precipitados.
Al final se corrigió el contenido del Mn, mientras que el Cu, Pb, Cd, Zn, Fe, y As, si cumplían con el LMP del D.S- 010-2010-MINAM y D.S. 015-2015-MINAM norma para ECA para aguas.

With the aim of contributing to the remediation of an area with acid mine effluents, the research consists of tests carried out at the Institute of Mining and Environment of the National University of Engineering, with the effluent donated by the mining company Coricancha. The objective of the present is the systematic fractionation of the acid mine effluent, which consists of precipitating the iron at a pH = 5 with the addition of the lime slurry, wait for the sedimentation to separate the liquid - solid phase; In the next step, to bring the liquid phase to a pH = 10 with the addition of the sodium sulfide, again wait for the sedimentation for the liquid-solid phase separation, finally to verify if the liquid phase complies with the standard DS- 010-2010- MINAM and D.S. 015-2015-MINAM, to pour the resulting water into the receiving body or recirculate into the system. At each stage, precipitates were obtained, which are called sludges, in the first stage of brown reds with a content of approximately 21.7% of iron and in the second stage of white beige with a content of 23.8% of zinc. The most abundant are sulfates and gypsum crystals. Then 4 briquettes of polished sections of these sludges were made, to carry out the microscopic study in order to know its mineralogical composition. In future research will seek the economic use of these precipitates. In the end, the content of the Mn was corrected, whereas the Cu, Pb, Cd, Zn, Fe, and As, if they complied with the LMP of D.S- 010-2010-MINAM and D.S. 015-2015-MINAM.
