In the processes of dissolution and adsorption of metals, the contribution of bacterial species previously adapted to specific environments, in order to achieve good results are required. In adapting Thiobacillus strains exist various mechanisms and reagents, as is the use of substances containing ideal nutrient media according to the effectiveness to achieve. For this reason we have modified the Middle 9k, with the aim of finding an appropriate means thereby increasing bacterial population isolated from strain Thiobacillus ferrooxidans Mining Salvage Unit, modifying the content of iron sulphate in the substrate and the strict control of pH . These values being 22.4 g / Lt iron sulfate and a pH of 1.8 A working conditions in the first 48 hours consumption of hydrogen protons is generated, which reduces acidity 2.3 - 2.4, with much less effect at low substrate concentrations. The producti...

Cultural expressions belonging to a particular subject area reflect the diversity of cultural identities by linking content, values and lifestyles (UNESCO, 2005), to develop goods and services would enable socio-economic inclusion of the Peruvian Andean peasant communities with products for a market potential is still existing in the study area. Problem: Which is the effect of the application of the workshop on the added value of the cultural products in inhabitants of small villages of the Comunidad Campesina Cruz de Mayo of Caraz, Ancash? In the meantime the inhabitants of two groups of houses are ignorant of that these products would be able to have value aggregation for the Peasant Community Cruz de Mayo of Callejón de Huaylas, Caraz, Ancash. Applied research, cuasiexperimental design; Previously scanned and posted the feasible products of cultural expressions, applying over oneself...

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.
