In recent years, conventional strategies for tailings management have been under increasing scrutiny by regulators, community leaders, environmentalists, and the shareholders of producing mine sites around the world. Engineers have been given too few viable alternatives due to costly manufacturing and limited applicability of existing technology. At last, technological advances in dewatering technology (most importantly filtration), in both productive capacity and consistency when applied to finer feed materials, have started to provide a far more attractive profile to companies who wish to pursue dry stack tailings facilities. This paper will address Dynacor Gold Mines’ pursuit of a tailings management solution for their newest mill expansion at their METALEX Beneficiation Plant in Peru. With an increasing daily capacity and an absolute limit on their current tailings disposal capacity, it was determined that a new tailings pond, along with four successive 50,000 m3 expansions, would have to be built at an extensive cost. Concurrently, Prevconsult Peru EIRL, with the assistance of CEC Mining Systems, conducted filtration testing and downstream engineering on the applicability of filtered dry stack tailings as a competitive solution for Dynacor. The joint proposal was successful in the application of thermoplastic filtration technology on Dynacor’s Au-‐Cn tailings stream. Filtration was able to provide consistent moisture contents (12%), while restraining the total project scope in order to remain cost competitive. The economic merit of this proposal has been combined with the mitigation of potential operational and downstream environmental liabilities, a simplified mine closure plan and the ability to implement progressive reclamation early on in the mine life. These results are a prime example of how technological innovation has facilitated a positive business case for the implementation of filtered tailings in combination with the measured environmental and operational benefits of a dry stack facility.
