Currently, the mining effluent corresponds to the discharge of the Pucara tunnel of the Ex Unidad Minera Goyllarisquizga than was a coal deposit, which was exploited by the former company Cerro de Pasco Corporation from 1907 to 1979,then was exploited by the state company CENTROMIN PERU until 1993. This year ceased to operate because the reserves got finished. Coal mining was carried out using the chambers and pillars method’s (until 1930), the Longwall mines (until 1971) and the open pit method until 1993. The Pucara tunnel is approximately 2 km long and since its inception it has been used to discharge the waters to the Ushogoya river basin, also the main access and extraction path for coal. In the last years (2000) it has been tried to close the tunnel with a hermetic plug, without positive results. This means that the tunnel continues draining acidic water, with a flow of approximately 30 l/s. Currently, the acid waters of the mining effluent are treated using a basic neutralization and precipitation treatment system and as reagents lime and flocculant to FLOPAM JC 7029. The products generated by the basic system reached relatively high volumes of sludge since 9 for 10 MT per day, which are difficult to handle and storage arrangement. In this thesis we will propose and improvement of the current acid water treatment system of mining efluent, to solve the main problem which is the high volume of sludge generated. Because of that we are going to proceed: first, by laboratory tests to determine the optimum flocculant: second, by jar tests we will determine the optimum concentration and rate of the reagents (lime and flocculant), as well as the flocculation and sedimentation parameters. Finally, the preliminary calculus and design of the aeration process, neutralization, oxidation and sedimentation base on the results we got in the laboratory.
