Aplicación del método concentración gravimétrica centrifuga con Knelson en relaveras para la recuperación de oro en material de granulometría fina en la concesión minera San Carlos

Abstract

Abstract:The present investigation is experimental, promoted by the Department of Geology and Mines and Civil Engineering of the Universidad Técnica Particular de Loja, is oriented to the application of gravimetric methods of gold recovery with tailings material inthe sector of "San Carlos" and was developed with sampling of tailings, for which it was supported by bibliographic material as well as a correct laboratory analysis and a cabinet analysis.For which an initial grade of 0.12 g/ton was obtained, the adequate parameters for an efficient recovery is a 25 min milling in which a granulometry of #120 mesh was obtained with 80% of passing material for the knelson tests with a water pressure of 1Psi and 60 G Forces where we obtained a concentrate grade of 2.27 g/ton and a yield of 70% considered as a good yield.The research project contributes to generate information on the application of centrifugal knelson gravimetric tests in mining, taking into account that these are not aggressive with the environment, for which an economic evaluation has been made to determine that the process with which we tested and is not favorable with the results obtained since the grade is too low, does not justify economically.
