Exploración y explotación de terrazas aluviales en la concesión "El Icho"

Abstract

The current research work proposes the following: Determining the gold reserves by means of the study of detailed exploitation in order to confirm the verified, probable and possible reserves in superficial supplies; to perform the exploitation of alluvial terraces at "El Icho" concession, Yutzupino community, Puerto Ñapo parish, Tena cantón, by using bibliographic, field research methods through the excavation of trenches and pools with bulldozers and a mini recuperation plant Trommel type, in order to determine the amount of verified, probable and posible reserves by applying the Influence Area method, and a recuperation plan Zeta type for the extraction of the mineral through cuts. The verified reserves were determined with a volume of 92616 m^ with a law of 0,38 g/mg^ which guarantee the recuperation of gold through outdoors exploitation works, takin into account the four main parameters: geometrical, geotechnical, operative and environmental, which allow to develop a design of outdoors exploitation system with filling over the mined áreas, by transferring the clay to the side, for furtherly takin out the chained gravel with bulldozers and start the cleaning process at the Z plant, to get high quality, low production costs, profitability, high performance and better work conditions for the personnel. For the casting process of the alluvial gold, it was used bórax as the main component, having a concéntrate with 80 of purity by gravimetrical systems such as the vibrating board. It is concluded that the amount of reserves obtained in the exploitation along the Basin of Yutzupino River is closely approximated to the exploitation data..
