This research‘s main objective quantification of iron content in sphalerites; differentiation of three types of sphalerites is obtained according to the iron content, which will be useful for the proposed solutions in the metallurgical problems. In this study themineralogical characterization of samples from the Paragsha concentrator, the mining district of Cerro de Pasco and especiallysphalerites using the method of optical microscopy was performed for which it was necessary to use a polarizing microscopereflected light.Studies was performed as accurately as in the case of modal analysis where estimates of the degree of liberation and mineralgicalassociation are made, the samples come from the metallurgical testing laboratory. The specimen was taken from the concentratorplant Paragsha, then sifted for the preparation of polished sections that were used for the characterization of each...

La presente investigación tuvo como objetivo principal la cuantificación del contenido de hierro en las esfaleritas; se obtuvo la diferenciación de tres tipos de esfaleritas según el contenido de hierro, lo que será de utilidad para la propuesta de solucionesen los problemas metalúrgicos. En este estudio se realizó la caracterización mineralógica de las muestras provenientes dela concentradora Paragsha, del distrito minero de Cerro de Pasco y, especialmente, las esfaleritas utilizando el método demicroscopía óptica, para lo cual fue necesario el uso de un microscopio de polarización de luz reflejada.Se realizó estudios de mayor exactitud como es el caso de análisis modales en donde se hacen cálculos del grado de liberacióny asociación mineralógica, las muestras provienen de pruebas realizadas en el laboratorio metalúrgico. La muestra de análisisha sido tomada de la p...

The present study includes the geochemical-statistical analysis of fourteen heavy metals in active sediments of the Huaura and Chancay rivers, in which the intrusive lithologies of the Batolito de la Costa predominate, and to a lesser extent the lithologies of the Calipuy and Volcánico Casma groups. Likewise, the metals that have a normal distribution are Fe and Cr and the lognormal distribution As-Cu-Cd-Hg-Mo-Ni-Pb-Sb-Sn-V-W-Zn. The average abundance shows that Zn, V, Cr, Pb, Cu are the most abundant metals and Mo, Cd and Hg occurs in small amounts. Pearson's correlation analysis in the Huaura River, the metals that best correlate are As with Cd, Cu, Pb, W, Zn and Cd with Cu and Zn, which indicate that it could have the same origin, while in the Río Chancay the metals do not have a good correlation, which would indicate that they do not have a common origin, except for the Cd with Zn ...

El presente estudio comprende el análisis geoquímico-estadístico de catorce metales pesados en sedimentos activos de los ríos Huaura y Chancay en los cuales predominan las litologías intrusivas del Batolito de la Costa y en menor porcentaje las litologías del Grupo Calipuy y Volcánico Casma. Asimismo los metales que tienen una distribución normal son Fe y Cr y distribución lognormal As-Cu-Cd-Hg-Mo-Ni-Pb-Sb-Sn-V-W-Zn. La abundancia media muestra que el Zn, V, Cr, Pb, Cu son los metales más abundante y el Mo, Cd y Hg se presenta en pequeñas cantidades. El análisis de correlación de Pearson en el Río Huaura los metales que mejor se correlacionan son el As con Cd, Cu, Pb, W, Zn y Cd con Cu y Zn, que nos indican que podría tener el mismo origen, mientras que en el Río Chancay los metales no tienen buena correlación lo que indicarían que no tienen un origen común, salvo el C...

The current geochemnical-statistical study involves thirty-seven chemistry elements involving fourteen of these called heavy metals such As, Cd, Cr, Cu, Fe, Hg, Mo, Ni, Pb, Sb, Sn, V, W, Zn collected in active stream sediments from Chilca, Mala and Omas rivers located in the department of Lima, Peru. The filonean mineralization ocurrences of Cu, Pb, Zn, the abundance of trace elements and the correlation multivariable of the elements in the three rivers reflects the prevailing economic mineralization, in the Chilca river Zn, Cd, Pb in Mala river Cu, Co, Cr and in the Omas river Cu, Pb, Zn. The other elements are not pathfinder of this mineralizations because of the absence of good correlation between them, suggesting different source, at the morfology of the deposit and the erosion level of the surface. It has been determined that Chilca River has exceeded permissible levels in As and ta...

Los cuerpos de serpentinitas con asociaciones menores de rocas máficas han sido interpretados como una intrusión de un magma ultrabásico profundo que se instala en forma de sills y diques en el seno de un conjunto metasedimentario de bajo grado atribuído al precámbrico, incluido en las unidades del Complejo del Marañón (Grandin et al., 1977 y referencias incluidas; Grandin y Zegarra, 1979). El emplazamiento del conjunto ultramáfico esta representado por varias etapas, primero la intrusión pre-tectónica en sills elongados en una secuencia sedimentaria de edad precámbrica y posteriormente los cuerpos gabroicos (íbidem). También se han interpretado los cuerpos ultramáficos como una inyección de tipo diapírico en secuencias del Paleozóico Superior (Megard et al., 1996).

The Metallurgical Mining Patrimony of Tinyahuarco (Smelter) is located 10 km southwest of Cerro de Pasco city, and between years 1906 and 1923, was the biggest foundry of the time that worked. The remains of the foundry deserve to be catalogued as a metallurgical mining patrimony because besides the infrastructure of walls and columns, which persist until today, also remain some parts like the furnace, the coke plant, some offices and the hotel; from them, the one that is in good condition, is the superintendent residence, which at the moment is inhabited. It is important to remark the history of the mining activity in this region that was transformed by the presence of the foundry of Tinyahuarco (Smelter), constructed with North American investments that helped to develop the mining industry with the best technology of the time, changing many social and economical aspects of the region ...
