Figure 47- Multi-Criteria analyses Advances in High-Throughput Filtration Systems The most transformative developments relate to next-generation high-throughput pressure filters. As outlined in How to Make Filtered Tailings Feasible, modern pressure filters now routinely handle very large tonnages while achieving substantially lower residual moisture levels—sometimes as low as ~5%, depending on ore type and process conditions. These improvements are the result of advancements in: • plate and frame design, • hydraulic systems, • filtration media durability, • cloth washing systems, and • real-time cycle optimization. Figure 48 Figure 6 depicts Larox FFP filters Metso’s global experience indicates that these new systems can operate safely and economically at capacities previously considered impractical for large copper and iron-ore operations. The adoption of automated, fast-cycle filters has been a “game changer,” enabling operators to reconsider filtration even in lower-grade, high-tonnage environments where energy and cost sensitivity is high. The “Addressing the Barriers to the Implementation of Filtered Tailings”(Calil, Palmer, Paste2026) paper further emphasizes that improvements in filter design, hydraulic control, and
