Abstract

These present research was carried out in the benefit plant "P G", Nambija sector, San Carlos de las Minas Parish, Zamora Canton; Province of Zamora Chinchipe. The purpose is to determine the efficiency process of the plant with the different processed used. It was sampled in a systematic way in different points such as: Head, trough, exit of the pipe, sluice concentrate. The mineral sampled from each of these points, they were taken to the laboratory of minerals benefit, to realize the corresponding essays. In mineralogical analysis, the following minerals determined were: quartz, calcite, hematite, minerals that constitute a skarn. The efficiency of the "P G" plant is 63.58%. The analyzed percentages of gold (Au) are: trough 45.26%, concentrate 18.32% and tailings 28.44%. Energy expenditure is 156.6 Kwh, considering three engines which were used in the process.
