Caracterización geometalúrgica de la mena del sector Tierrero-Nambija de la Empresa Minera Macas, para el proceso de recuperación de oro mediante procesos gravimétrico y metalúrgicos

Abstract

Abstract:The objective of the following work is to recover gold from the "Minera Macas" beneficiation plant. applying gravimetric and metallurgical concentration methods, with material obtained in the work front, in order to obtain a higher yield of the mineral. For him This work required bibliographic material and the execution of laboratory tests. As results, a head grade of 252 g/T was obtained, the parameters used for the gold recovery (Au) are: the granulometry with a grinding time of 40 minutes obtaining a particle size of 80% in the #200 mesh and 33% solids for both Knelson, flotation and cyanidation respectively. For the Knelson concentration, 60 was used. G forces and 1 Psi achieving a yield of 84%, for flotation we worked with a pH of 9- 10 and with a collector concentration of 50% achieving a 75% performance and for cyanidation a cyanide concentration of 0.8 g/l and a pH of 10.5-11.5 obtaining a yield of 81%, thus performing an evaluation of all the processes, a 86% yield.
