881 Figure 13. Pilot Plant General Arrangement 4. SUBMISSION AND DISCUSSION OF RESULTS Based on the above, the following results were determined: ● Antamina defined the technical feasibility of dewatering its tailings using tailings technology: cycloning-screening. ● Antamina defined the optimal mixing ratio range of 4:1 based on various field tests and trials conducted, considering geotechnical-geochemical equilibrium and operating parameters. ● Antamina determined the number of single cycloning stages needed, achieving an average moisture content of 15%, preventing liquefaction during tailings transport and storage, and a split of 65%. This minimizes the amount of fine tailings sent to the existing tailings storage facility, allowing postponement of raising the facility. ● Antamina defined the type and size of crushers to be used in the mechanized system to meet the requirements of the mining plans. ● Antamina defined the disposal plan for the Commingling project, aligned with the project phases and the unloading through trucks. ● Antamina determined that the transport of the mixture does not cause segregation due to the vibrations inherent in the mechanized system18. 18 It will be re-confirmed in the Pilot Plant
