Monitoring and PH Analysis of Tailings from the Effluents of the Cerro De Pasco Mining Company in the Years 2017-2021

Abstract

Currently, mining operations in Peru, such as in the province of Pasco, require water consumption for metallurgical mining processes, supply for personnel, among other operations. The purpose of this study is to determine whether the mining company located in Cerro de Pasco has reduced its pH values over the years and whether they are within the Maximum Permissible Limits established by Peru. The impacts of mining activities cause damage to water bodies and the health of the population, so water monitoring is carried out at certain discharge points called cell1, cell2 and cell3, where pH measurements were taken. The results of the monitoring, with respect to the tailings from the mine, are acidic pH values containing suspended solids as well as high concentrations of sulphates and metals. The contributions of the study, which is carried out in the city of Cerro de Pasco located at 4338 m.a.s.l., show practical results as they are used for a diagnosis and analysis for the years 2017-2021 with respect to the mine tailings.
