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...

The sample which is the subject of this research work is the process of amalgamation tailings, from the district of Lomas, department of the Piura. Provided by the miners in the area. The mineralogical characterization of the samples showed the presence of the following minerals: gold, electrum, pyrite, arsenopyrite, hematite, goethite and ganges. Tests were conducted metallurgical concentrator Falcon to different forces of gravity: 40, 50, 60, 70 and 80 G’s, with a particle size of 56.55% - 200 mesh. Metallurgical balances indicate that the best evidence is gathered with 60 G’s, obtaining a concentration of 82.78 g/TC, recovery of 17.76% and 28.55 radio concentration. The results indicate that these teams mostly work as preconcentration. The head trial of this amalgamation tailings is 18.69 g/TC gold and 4.62 ppm of mercury, the average calculated heads is 16.16 g/ TC gold and 3.64 ...

This research aims to explore possible solutions to the problems presented in auriferous sulfide minerals , which have cianicidas by metals ( Gold companions ) can not be cyanide by high reagent consumption , which makes the process uneconomical . Also be a problem hitting the small domestic mining sites that have these features that can not be traded concentrates by high penalties imposed on them , then creating a social problem that should be taken into account. At the experimental level by testing and subsequent acid leach cyanidation seek to find a process that allows for adequate separation of gold copper and other species also have high technical and economic efficiency. Exploratory tests shown indicate the feasibility of finding the right process for the investigated mineral content has Gold , chalcopyrite , malachite , magnetite , hematite , goethite , covellite , chalcocite , an...

Prospective studies developed in the zone of the Marañón basin show us a type of regional geology called the Marañón-Huánuco Region Complex, consisting of metallic minerals of Copper, Silver, Gold in schists and gneiss in contact with intrusives, as well as minerals of nickel, cobalt, titanium, platinum, among others. The characterization of the minerals in the area using instrumental techniques: minerographic microscope, Mössbauer spectroscopy analysis, multielemental chemical analysis, allow us to corroborate the presence of the metallic minerals of the Marañón Complex, as well as the presence of iron oxides, and to a degree of magnetization that are indicators of the metallic presence in the sampled areas. Metallurgical tests carried out indicate a good metallurgical recovery of the concentrates obtained for the chalcopyrite ore, which indicates a good economic possibility for...

Estudios prospectivos desarrollados en la zna de la cuenca del Marañón nos muestran un tipo de geología regional denominada Complejo del Marañón-Región Huánuco, consistente en minerales metálicos de Cobre, Plata, Oro en esquistos y gneis en contacto con intrusivos, así como también minerales de níquel, cobalto, titanio, platino, entre otros. La caracterización de los minerales de la zona mediante técnicas instrumentales: microscopio minerográfico, análisis por espectroscopia Mössbauer, análisis químico multielemental, nos permiten corroborar la presencia de los minerales metálicos del Complejo Marañón, así como la presencia de óxidos de hierro, y con un grado de magnetización que son indicadores de la presencia metálica en las zonas muestreadas. Pruebas metalúrgicas efectuadas nos indican una buena recuperación metalúrgica de los concentrados obtenidos para el...

The representative sample of low grade sulphide ore gold for this research study comes from the province of Casma Ancash department. The characterization of the sample was analyzed in the polarized light microscope, in the EAP. Geological Engineering at the National University of San Marcos (UNMSM), the results indicated the presence of the following mineralogical species such as Electrum, sphalerite, ilmenite, pyrite, hematite, goethite and bargains.

El metamorfismo en el área Quebrada Totorita-Lunahuaná es principalmente de tipo “Metamorfismo de Contacto”, mostrado en el trabajo de campo, caracterización de unidades geológicas, y afianzado con la petrografía de secciones delgadas. Relacionado a este, se reconoce una zona de fuerte alteración hidrotermal por la presencia de biotita, pero de extensión muy local, lo cual sugiere una posible ocurrencia metálica de un Pórfido de Cobre- Skarn.

The mean metamorphism at Quebrada Totorita, Lunahuaná, is “Contact Metamorphism”-type, according to the fieldwork, characterization of geological units and supported with thin sections petrography. A strong hydrothermal alteration of biotite was recognized associated to the metamorphism, although with very localized extension, which suggest a probable metallic occurrence of Porphyry Copper-Skarn.Key words: 

The sample that is the object of this research work is a kind of bituminous coal, from the Mount Huáscar, province of Oyón, department of Lima. Provided by the Coal Mine Company. The mineralogical characterization of the sample coal, to show the presence of the following minerals: Graphite (grf) and Pyrite (py). The percentage distribution indicates graphite and 96,91% 3,09% pyrite, the particles are mostly free, accordingly modal analysis indicates that the degree of liberation of graphite and pyrite is 100%, that is counted all particles are free, as can be seen in the photos N.º 1, 2 ,3 and 4. Based on the characterization done it can be concluded that sulfur is in the pyrite, which is the polluter coal. Metallurgical tests were conducted preliminary gravity and flotation; being the outcome of the gravity is not satisfactory. The three tests metallurgical more representative of flo...
