Evaluación de los procesos productivos en la minería artesanal, sector La Pangui, distrito minero Chinapintza

Abstract

The present research concerns about the "Evaluation of production processes in artisanal mining in “La Pangui- Chinapintza" sector. It was performed in order to establish the recovery efficiency of the "SJ" plant, as well as the water and electricity consumption in the process; In order to develop this research five points of the grinding process were sampled: head material (P1), launder (P2), tube outlets (P3), wadding (P4) and tailings (P5). In the process a specific weight of 3.52 g/cm3 was determined. The main minerals identified were: quartz, pyrite, albite, sphalerite, muscovite, galena. The evaluated screen value analysis determined that the highest percentage of gold in P2 is found in mesh # 60 with 47.26% and P4-P5 have their highest gold concentration in mesh # 120 with 57.74% and 39, 80% respectively. The gold grades that were determined in laboratory are: P1= 23.57 g/ton, P2= 1282.92 g/ton, P3= 18.5 g/ton, P4= 992.28 g/ton P5= 13.38 g/ton. Additionally, it was determined an efficiency of 85.23%. Finally, the water consumption obtained was 839.06 m3 as well as an energy consumption of 1775.547 kWh.
