The research carried out proposed analyzing the impact on the implementation of the social and environmental development programs of the Minera Barrick company, for which the Pierina-Huaraz Production Unit focused. For this, an elementary type of investigation was used, making use of an investigative design of a quantitative nature, in strict compliance with academic rigor. The universe considered in the present study was the community of Cuncashca, Mareniyoc, Mataquita and Atupa, corresponding to Jangas, belonging to Huaraz which have a population of 767 inhabitants, distributed in 330 homes, for which in reference to the study, it was considered a sample of 75 families from nearby towns, applying an instrument of 15 dichotomous questions, which I take into consideration are those related to the significant contributions that are provided to neighboring communities, corresponding to sus...

Evalúa la efectividad del Programa Integral de Responsabilidad Social y Ambiental (PIRSA) de la Empresa Minera Barrick en la Unidad de Producción Pierina, ubicado en el distrito de Jangas, provincia de Huaraz, departamento de Ancash. La metodología utilizada es una investigación básica con un diseño no experimental, nivel descriptivo, enfoque cuantitativo y corte transversal. La población estuvo conformada por las actividades del Programa PIRSA en las 12 comunidades aledañas a la Mina Pierina. La muestra estuvo conformada por 75 viviendas de 4 comunidades (Mataquita, Mareniyoc, Atupa y Cuncashca). Se aplicaron dos instrumentos, uno para medir el nivel socioeconómico de las poblaciones, y otro para medir la variable responsabilidad social y ambiental. Los resultados descriptivos demostraron que el 37.9% de la población se dedica a las actividades del hogar, 31.3% actividades ind...

The gold-silver artisanal operations carried out throughout the Peruvian territory are characterized by having low recoveries of precious metals, being carried out in poor working conditions and generating negative consequences in the ecosystem, which was the basis of the approach to our problem. For this, a representative sample of a batch of amalgamation tailings in the department of Puno was investigated with a tested head of 19.58 gr/TM of Au, 159.67 gr/TM of Ag and 10.53 ppm of Hg. The optical microscopy report indicated the presence of gold, pyrite, magnetite, hematite, Ilmenite, rutile and gangue. With the results of the mineralogical characterization, leaching tests were carried out with ecological reagents for a sample with a regrind granulometry of 87 microns, such as: Sandioss, which reached a recovery of 99.25% Au and 93.14% Ag, with a consumption of 22.56 kg/TM for a period ...

The Bismuth Brass Material which microstructure is formed by α and β crystals presents Bismuth inclusions in the grain boun- daries and in the grain. The Bismuth-Selenium Brass Material which microstructure is formed by α and β crystals presents Bismuth inclusions in the grain boundaries and in the grain; Selenium is presented in the grain boundaries. The mechanical properties are the following: Mean Properties I II Tensile Strength, Mpa 385 387 Yield Strength, Mpa 180 175 Elongation % 38,8 40,5 Hardness, BHN 110 112 The speed of electrochemistry corrosion in mpy, according to Tafel is the following: Material I Tap Water: mpy = 0.998 NaCl Solution at 3.56% mpy = 1.065 Material II Tap Water: mpy = 0.970 NaCl solution at 3.56%: mpy = 1.105
