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 ...

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...

La muestra de estudio es mineral refractario con ley de 19.31 g,/TM proporcionado por los mineros artesanales de Yangas, provincia de Canta, departamento de Lima. La caracterización mineralógica de la muestra tiene minerales de: Oro, Calcopirita, Covelita, Calcosita, Esfalerita, Pirita, Arsenopirita, Magnetita, Hematita, Goethita, Rutilo y Gangas como se indica en tabla 1.Los minerales de mayor volumen son: Gangas, Pirita y Calcopirita, el oro es de 17 micras.

El trabajo de investigación se basa fundamentalmente en estudiar los iones Pb, Zn, As, Sb y Ag y su influencia en la activación de la esfalerita durante l a flotación del plomo, cuando hay est e probl ema, se contamina el concentrado de plomo y disminuye el zinc en su circuito. Se ha trabajado con tres muestras de minerales con diferentes grados de activación del zinc, los resultados indican que el cont enido de i ones As requi ere más investigación para aclarar si es o no c ausante de l a fl otación natural del zinc, y las sal es solubl es de Pb, Zn, Sb y Ag no influyen en la activación natural de la esfalerita.

The contribution of mineralogy is essential in modern mining studies. Its importance lies in the qualification of mineral deposits and in what has been designated as process mineralogy, this concept has taken force due to the different uses in the processing of mineral deposits. Mineralogical studies provide information on the different classes of minerals and their peculiarities. This provides information to explain the results obtained in the different metallurgical tests and determine the potential that could affect the processing. As it is decisive to establish the disposition of the minerals in the deposit, we need to apply the different mineralogical characterization methods such as X-ray diffractometry, electron microscopy (microprobe and scanning), optical microscopy, among others. These resources are used together, being complementary to obtain complete information. This researc...

The ores of manganese are difficult to concentrate, nevertheless in this study of research, it has been achieved to raise the grade of manganese applying different equipments, machines, flow charts and diverse chemical reagents of flotation, obtaining the best results by means of flotation of the gangue, being the tail the concentrate of manganeso. The original ore has 23,8% Mn, on having it concentrate by inverse flotation, one manages to obtain 47,50% Mn in the concentrate, product very quoted on the intermal and external market.
