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. Furthermore we found particles referred to gold, which are: Electrum-goethite, Electrum-Gangas, Electrum-goethite-Gangas. Based on the results of the characterization we realized metallurgical process like preconcentration Falcon performed in the concentrator, the results of the most representative process is 67.80%, obtaining in a granulometry of -200mesh, obtaining a concentrate grade of 16.20 g / TM, 57.04% of 41.60 radio recovery and co...

La muestra representativa del mineral sulfurado de baja ley de oro, para el presente estudio de investigación, proviene de la provincia de Casma, departamento de Áncash. La caracterización de la muestra se realizó en el microscopio óptico polarizado, de la EAP Ingeniería Geológica de la Universidad Nacional Mayor de San Marcos (UNMSM). Los resultados de esta caracterización indicaron la presencia de las siguientes especies mineralógicas: electrum, esfalerita, ilmenita, pirita, hematita, goethita y gangas. Además, en la muestra encontramos partículas entrelazadas referidas al oro, las cuales son: electrum-goethita, electrum-gangas, electrum-goethita-gangas. Según los resultados de la caracterización, se realizaron pruebas metalúrgicas de preconcentración a la muestra, con el equipo de concentración Falcon; los resultados de la prueba más representativa obtenida a una gran...

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...
