Resumen
La presente tesis trata sobre la identificación de la o las asociaciones minerales con mayor contenido de oro presentes en la veta denominada Calderona. El trabajo se llevó a cabo en la ciudad de Zaruma, provincia de El Oro, en la mina Amistad, área minera Amistad. La metodología utilizada se dividió en 2 partes, la primera comprendió el levantamiento topográfico, seguido de recolección de muestras de punto para su posterior descripción macroscópica y análisis en laboratorio, la segunda parte consistió en realizar los mapas de concentración de oro y plata, además de mineralógicos utilizando como software para la representación el AutoCAD.
Se concluyó que la mayor concentración de oro en la veta Calderona en la mina Amistad está relacionada con las zonas oxidadas, a partir de la alteración de los minerales primarios y su lixiviación, y la asociación mineral con mayor contenido de oro es Cuarzo-Goethita-Jarosita, además que en los sectores donde la veta presenta gran potencia los valores de oro aumentan.
The present thesis deals with the identification of the mineral association (s) with the highest gold content present in the Calderona vein. The work was carried out in the city of Zaruma, El Oro province, in the Amistad mine, Amistad mining area. The methodology used was divided into 2 parts, the first comprised the topographic survey of the mine, followed by the collection of point samples for later macroscopic description and analysis in the laboratory, the second part consisted of the gold concentration maps and silver, in addition to mineralogical software using AutoCAD. It was concluded that the highest concentration of gold in the Calderona vein in the Amistad mine is related to the oxidized zones, due to the alteration of the primary minerals and their leaching, and the mineral association with the highest gold content is Quartz- Goethite-Jarosite, in addition that in the sectors where the vein has great power gold values increase.
