In this paper the technological innovations and increased tonnage treatment will introduce in processing ore open pit mine is described. To counter the instability and falling copper prices on the world market and the fall of the treatment head in U.M. Chest Ciemsa is necessary to increase tonnage and metallurgical treatment of recovery, which produced fine for marketing content increases and thus generating more favorable company earnings Due to operational disadvantages with the helical classifiers and hydrocyclones, sieves are deciding to use high frequency to be sized particle in the second grinding step. The classification is done in hydrocyclones difference in size and specific gravity, while the separation zaranda high frequency is exclusively particle sizes. According to the experiences of the papers presented by Mina El Brocal and Condestable, in both cases the advantage of increased tonnage are between 20 and 40%, and decreased the circulating load by 50%, also decreases quite over-grinding sizes less 10u, ie the generation of lamas is going to reduce this effect helping to improve problems in the stage of flotation and other sections. Based on the data of the mass balance of 530 TMSPD. The finished work is to evaluate the processes of increasing treatment in a 50.94% increase to produced (800 TMSPD) with a mesh release of fine particles of 65.07% -200m, implementing a Zaranda High Frequency, battery cyclones and D10 a ball mill 6'Øx6 'recently acquired. The Shale High Frequency (STACK SIZER), acts as a team desliming since the panels are with meshes of 300 microns, this in order to quickly remove below 300 microns and thus reducing the circulating load of 192% (TMSPD 530) to 122% (800 TMSPD), generated in the grinding process, The metallurgical recovery increase significantly due to good grain milling, despite the increase in tonnage of 76.93% treatment (530 TMSPD) to 78.78% (800 TMSPD). The economic impact of the expansion was evaluated, the monthly and annual profits produced, according to the recovery of copper concentrate is analyzed.
