ABSTRACT The overall objective of this thesis is to improve gold recovery in a process of agitation leaching (cyanidation bottle) evaluating the parameters of cyanide concentration and particle size from an oxide ore zone district Cachachi, Cajabamba, Cajamarca. The hypothesis of the research is; as it increases the concentration of cyanide and decreases the particle size increases the recovery of gold. The technique of experimental research used was bifactorial carried out 3 levels of free cyanide concentration (ppm): 400, 600 and 800 with three levels of Grit: # 100, # 140, # 200, which was analyzed by agitation leaching with evidence cyanidation in bottles. The greater recovery of all tests performed was at a concentration of 800 ppm cyanide and a grain size # 140 mesh, with a recovery of 91.47% was obtained. Even with this value can consider that the recovery is low compared to other outcomes investigated and this is mainly due to the presence of other metals that act as cianicidas which make it an uneconomic process. We also apply the statistical study of Analysis of Variance (ANOVA), which will allow us to determine our investigations, if there are significant differences or otherwise can be assumed that their population means do not differ, according to our two study variables, resulting in the following hypothesis: the concentration of CN if it affects the recovery of gold; Particle size if it affects the recovery of gold and the interaction of CN concentration and the particle size if it affects the recovery of gold. Finally a preliminary study of the installation of a processing plant minerals in order to see the profitability of our process gold recovery was made, the data represented are real as possible, resulting in a NPV of 2,718,241 and IRR of 42%. This brings us to the conclusion that this project is viable and profitable.
