Abstract

In this report we have worked with ore of 60.12 kg total -10 #Ty. Where various tests were done in order to characterize and evaluate the mineral to work according to the benefit of copper. In such a way that 0.27% humidity has been obtained through a moisture test using a drying furnace. For its density, through 10 measurements, an average of 3.06 g/mL is obtained considering as the actual density. A granulometric analysis was carried out with a mass of 496 g, so that a 1258.56 µm is obtained, in addition to adjusting with the least error to the parameters of Gaudin-Schumann. And, mainly, a chemical analysis whose percentage of copper was 1.62% total, iron of 19.53% and molybdenum of value 0.02%. Subsequently, grinding tests were performed, after characterizing the ball collar and the optimal grinding time of 19 minutes, after skimming and obtaining 60% through the 200 mesh. Finally, flotation tests were performed with different collectors, in variations of 10 to 30 g/t dosage, leaving in evidence a better recovery for the foaming DF-250 to 30 g/t dosage and the primary and secondary collector Hostaflot x-23 and Aero 3477 Promoter respectively, reaching a value of 84.72% so that with these reagents, flotation kinetics tests were performed, achieving a scale of 8.71 minutes of flotation to 17.41 minutes in industrial scale with the kinetic model of Klimpel. Finally, after several tests, it was determined that the technical proposal on float represented by a flowchart with the dimensions of the main equipment.
