The mineral That is matter of the present work of investigation comes from the department of the Libertad, province of Otuzco, the mining company Koricolqui S.A. The study by the x- rays diffraction confi rms that the greater component of the sample is guartz in 91,74 %. In the characteristic of the sample by the method by polarizing microscope of refl ected light, the following minerals are observed: electrum, arsenopirita, marcasite, calcosita, galena, esfalerita, rutilo, goethite, tetraedita and gangues; which are like very small particles that they make diffi cult his treatment. The tests of fl otation of the initial sample are not satisfactory because the recoveries are as much for low gold and silver that is of 59,11% and 52,51% respectively. For that reason previously I am made a preconcentration with the centrifugal “Falcon” and relave of the “Falcon” just enters the fl o...

The worldwide demand for silver is increasing due to the technological development in different areas, especially for the requirements in the production of renewable energies; therefore, for the treatment of refractory minerals by conventional processes, it is necessary to study mechanisms to identify the viability of their processing and the feasibility of their recovery, ensuring profitability. Gold and silver present in the matrix of sulfide-based ores are not affordably recovered by the conventional method involving leaching in sodium cyanide solution. Therefore, it must be subjected to oxidation pretreatment or conversion of the sulfides to simple compounds that allow recovery of the precious metals. The methods of oxidation of minerals considered refractory are carried out by hydro and pyrometallurgical methods, seeking the dissolution of sulfur, iron, arsenic and other elements pr...

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 con...

La muestra representativa del mineral sulfurado de baja ley de oro, para el presente estudio de investigación proviene de la provincia de Casma del departamento de Ancash.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.En base a los resultados de la caracterización se realizaron pruebas metalúrgicas de preconcentración a la muestra, con el equipos de concentración Falcon; los resultados de la prueba más representativa obtenida a una g...
