In the southern part of Peru, it is found Zn-Pb-Cu-Ag-Au mix ore carbonate deposits and polymetallic sulfides in volcanic rocks. It is known that such types of ores are difficult to process, so this ore was tested by leaching using solutions containing hydrogen peroxide and ammonia (H2O2 / NH3); which are, respectively, the oxidant and the complexings agent. Lab work was done with a mix ore, (oxides and sulfides), containing copper, silver, gold and zinc in the form of chalcopyrite, bornite, brochantite, proustite, marmatite, pyrite and few amounts of lead oxide; gangue, basically carbonates. Using H2O2 / NH3, and pH fixed between 9 to 10, metallic recovery was gotten close to 90 % for copper, gold, silver and zinc. Lead and iron do not dissolve in alkaline solution. Metals recovery was done by redox cementation with metallic zinc, which allowed gold, silver, and copper precipitation, th...

The mining industry of porphyry copper deposits process complex and low-grade minerals (Romero Toledo et al., 2017). One of the problems related to this practice, is the type of mineral, harming the mining - metallurgical treatment that affects the consumption of excessive energy and the critical recovery of economic minerals (Mudd, 2010). The objective of the research was to analyze the mineralogical characterization; then to contrast the behavior of the minerals in the process of flotation of minerals in the porphyry deposits of copper and with it to implement improvements (Díaz Villena, 2017). The techniques used were X-ray diffraction, optical-electronic microscopy (Manzaneda Cabala, 2010) and chemical analysis. They provided reliability and support to determine qualitatively and quantitatively the mineral phases that cause problems in the flotation of copper minerals  (Donoso ...
