Evaluación de los Procesos en la Planta JD, sector La Herradura, distrito Minero Chinapintza, provincia de Zamora Chinchipe.

Abstract

This research was conducted in the mining area "La Herradura" located in the mining field Chinapintza, parroquia Nuevo Quito, cantón Paquisha; in the province of Zamora Chinchipe, in order to determine the efficiency of two artisanal process such as gravity concentration and cyanidation, development was carried out systematic sampling of the material, resulting in performance variables such as: specific gravity, mineralogy, grain, valued and tenors gold and silver mesh. Obtaining 2.87 g / cm3 in specific gravity; sphalerite, pyrite, quartz, rhodochrosite, microcline, and biotite in cerusita mineralogical analysis; the D80 in the particle sizes most were between the mesh # 60 and # 120, in the meshes valued the highest percentage of gold mesh # 200 and # 400, gravimetric concentration 7.73 g / t gold was obtained and 100.40 g / t silver. In cyanidation an income of 89.84 grams of gold and gold in cyanide solution recovered 53.60 g was obtained. Gravity concentration at 54% efficiency was obtained, while the efficiency cyanidation process is 60%.
