Recuperación de oro por flotación del mineral de mina del área minera SAN VICENTE en Zamora Chinchipe

Abstract

Abstract: The purpose of this research work, called Recovery of gold by flotation of mineral from the SAN VICENTE mining area in Zamora Chinchipe, is to determine the optimal parameters (particle size, pH and type of collector) of the process, as well as to carry out a comparison of their influence on gold recovery by flotation in a Denver cell. For this, four flotation tests are carried out, varying the aforementioned parameters. Accompanying these flotation tests, an X-ray fluorescence analysis (FDX) is carried out, which allows the identification of the main components of the mineral sample. A mineralogical analysis is also carried out by means of X-Ray Diffraction (XRD), to determine the minerals that make up the sample, with quartz and pyrite being the majority. Once all the corresponding tests and calculations have been completed, an economic evaluation of the flotation process is carried out on a laboratory scale, for which the highest recovery percentage and the current costs of gold and the reagents used in the process are used.
