Metso launches Sampo Cell

Mineral processing equipment specialist Metso has officially introduced the Sampo™ Cell, a groundbreaking innovation in coarse particle flotation aimed at transforming mineral recovery efficiencies across the global mining sector. As Zambian mining houses grapple with the challenges of declining ore grades and the necessity to process more complex orebodies, technological advancements of this nature carry profound implications for the Copperbelt. By enhancing the recovery of coarse particles without compromising fine particle recovery, the new technology offers a pathway to optimized throughput and reduced operational costs. Traditional flotation circuits have long depended on extensive and energy-intensive grinding to reduce particles into an optimal range for efficient recovery. However, the Sampo Cell shifts this operational paradigm by expanding flotation performance to significantly coarser and less liberated particle sizes. Utilizing an innovative froth-feeding principle, the system gently introduces slurry directly into the froth phase under low-turbulence conditions. This minimizes particle detachment and successfully recovers valuable minerals that are typically lost in conventional circuits, functioning effectively either as a front-end gangue rejection tool or as a scavenger stage. Significantly, the design simplifies conventional coarse particle flotation flowsheets by operating entirely without feed classification, fluidization water, or additional concentrate dewatering stages. For Zambian mining operations striving to optimize water management and lower energy consumption—particularly in light of recurring power constraints and environmental compliance pressures—such streamlined integration is a welcome prospect. The technology utilizes standard flotation controls and instrumentation, ensuring that plant operators can implement the system without undergoing complex automation overhauls.
