Abstract

The main objective of the research is to analyze the origin of metallic minerals in the province of El Oro, Portovelo-Zaruma District, by means of a bibliographic review to know their uses, economic value, utility and benefits; where it is established as specific objectives to study the uses of metallic minerals in the mining district; in addition to identifying the economic value of the metallic minerals extracted in the present district and establishing the usefulness and benefits of the metallic minerals extracted in this district, where based on the scientific collection of various primary bibliographic sources that is established, where the mining activity , is the base of the main sources for the economic development of the province of El Oro. The Portovelo-Zaruma mining district located to the South of the Western Cordillera corresponds to an epithermal of intermediate sulphidation that contains veins of Au, Ag, Cu, Zn, Pb and is made up of metamorphic and volcanic rocks.
