Recuperación de oro de material de mina proveniente del Distrito Minero Chito, provincia de Zamora Chinchipe, a través de la aplicación de métodos metalúrgicos extractivos

Abstract

Abstract: The purpose of this TIC is to recover gold from two veins in the Chito mining district Zamora Chinchipe of the Sangola Project, based on a non-systematic grab-type sampling sampling for the Rocky vein and a chip sampling for the Osan vein, which will be applied physical, chemical and mineralogical characterization to determine operational parameters of concentration processes. At the Knelson concentration the same parameters for carrying out the test of both veins, obtaining a performance of process of 41% for the Rocky vein and the Osan vein, a yield of 23.23% was obtained. He The second process was concentration by flotation, where the reagents used for the vein Rocky were the Z6 primary collector, MT-4095 secondary collector, 370 foamer and sodium silicate depressant, obtaining a yield of 96%, as for the Osan vein used Ox-10S oil reagents as primary collector, Orex-936 secondary collector, Flo-655 foaming agent and sodium silicate as a depressant, achieving a yield of 89.1%. Finally, cyanidation tests were carried out and the same parameters were used operational, achieving returns of 43.3% for the Rocky vein and 49% for the Osan vein.
