Endomines’ Sofi Recovery as a Service at Pampalo: economics and flowsheet notes

First reported on International Mining – News
30 Second Briefing
Endomines Oy has moved Sofi Filtration’s Sofi Alchemist Recovery as a Service system from pilot to full-scale operation at the underground Pampalo gold mine in Ilomantsi, eastern Finland. The cloud-connected filtration and recovery platform is designed to capture fine gold particles from process streams that would otherwise report to tailings, improving overall plant recovery without major changes to the existing concentrator flowsheet. For metallurgists, the as-a-service model shifts capex to opex and enables continuous optimisation of recovery performance via remote monitoring and software updates.
Technical Brief
- Recovery as a Service contracts typically bundle hardware, automation, maintenance and performance monitoring into a single operating fee.
Our Take
Sofi Filtration’s move from establishing a test centre in Izmir, Türkiye, to deploying its solution at Endomines Oy’s Pampalo gold mine in Finland signals that the company is now progressing from regional piloting to full-scale commercial references in hard‑rock mining.
Within our gold‑tagged mining coverage, relatively few pieces focus on Nordic underground operations like Pampalo in Ilomantsi, so this deployment gives Sofi Filtration a showcase in a jurisdiction known for strict environmental regulation and water‑quality standards.
For Endomines Oy, adopting a Recovery as a Service model at a Finnish gold asset suggests a strategy to de‑risk capex on process‑water upgrades, which could be attractive for other mid‑tier Nordic gold operators facing similar permitting and tailings‑water constraints.
