In the present work, the recovery of gold by the acid leaching method with constant stirring from a highly refractory ore from the metallurgical laboratory of the National University of Trujillo, Faculty of Metallurgical Engineering (Law 2.84 onz Au / TM); the independent variables were evaluated as the concentration of thiourea solution and agitation time. The granulometry of the refractory mineral was 100% solids and 200 mesh and the tests were carried out in the mineral processing laboratory of the metallurgical engineering department. In the experimental part, they were carried out for cylinder stirring tests for 72 hours of constant stirring and chemical composition of the refractory mineral, by means of dry-run analysis and atomic absorption, and the statistical analysis of the student test was performed for a single sample of data and has the most significant variables in the gold...

In this research gold recovery was performed by the method of acid leaching with constant stirring from a highly refractory ore from the metallurgical laboratory of the National University of Trujillo, Department of Metallurgical Engineering (Law 2.84 oz Au / TM); the independent variables was evaluated as the concentration of thiourea solution and stirring time. The particle size of the refractory ore was 100% solids and mesh No. 200 and the tests were performed in the laboratory mineral processing metallurgical engineering department. In the experimental part were performed to test turmoil in bottle for 72 hours of constant agitation and chemical composition of refractory ore, by analysis on a dry basis and atomic absorption and student test for a single sample of data statistical analysis was performed and is the most significant variables in gold recovery for this research, is the co...
