882 5. CONCLUSIONS The Commingling technology can change current conventional Tailings Management or even eliminate or reduce the conventional dam-deposit footprint. This new approach could unlock land and environmental constraints in the mining industry: ● The Commingling project is an optimal enabler for Antamina's Life Extensions. ● The Commingling project enables optimization of Antamina's tailings strategy, which is naturally aligned with the GISTM (Global Industrial Standard for Tailings Management). ● The Commingling project is an innovative solution that contributes to improved environmental management in the mining industry by minimizing disturbed footprints. ● The optimal tailings technology for Antamina is cyclone-screening. ● The optimal ratio range for mixing was defined as 4:1 (crushed waste rock: dewatered tailings) ● Antamina requires only one cyclone stage to achieve the moisture and shear required for a homogeneous mixture, allowing for geotechnical and geochemical equilibrium. ● The Commingling project allows for postponing the raising of the dam at the current tailings storage facility because only the fine fraction (35% of total tailings production) will be sent to the tailings storage facility. ● The Commingling project enables the optimization and reduction of mining trucks through the installation of a mechanized system.
