en.Wedoany.com Reported - Finnish water treatment technology company Sofi Filtration Oy announced on June 23, 2026, that it has delivered the first Sofi Alchemist system to the Pampalo gold mine in Ilomantsi, Finland, operated by gold producer Endomines Finland Plc, and has officially commenced large-scale recovery operations. The system is designed to recover ultra-fine concentrate particles from process water while enabling the purification and reuse of process water. During the pilot phase completed in 2025, the system achieved up to 99% recovery of fine concentrate from process filtrate.

Endomines Finland Plc is a Finnish sustainable mining company listed on the main market of the OMX Helsinki Stock Exchange (ticker: PAMPALO). The company's core business focuses on the mining and processing of the Pampalo gold mine, as well as exploration activities in the Karelian Gold Line region in eastern Finland. The Pampalo gold mine is located in the Ilomantsi area of eastern Finland. In the spring of 2026, Endomines launched a regenerative mining model called "AliveMine," aiming to achieve sustainable development in the mining industry by combining environmentally responsible operations, data-driven decision-making, and close community engagement.

Sofi Filtration is a Finnish water treatment technology company specializing in ultra-fine particle filtration solutions for mineral recovery and dedicated to the purification of industrial process water. The company's technology helps industrial customers maximize resource efficiency and reduce waste. The Sofi Alchemist system is an innovative filtration technology developed by Sofi Filtration. When processing mine by-products—excess process water generated during production—the system recovers valuable minerals that would otherwise be wasted. The technology operates without the need for chemicals or disposable filters, can separate particles as small as 0.3 microns, and features self-cleaning functionality without disrupting the main production process.

This deployment adopts an innovative business model called "Recovery as a Service," under which Sofi Filtration owns and operates the system. Endomines Chief Operating Officer Ilkka Räty stated that this collaboration provides valuable new data for process improvement, and he is particularly looking forward to the potential for increased recovery rates and tangible commercial benefits. Sofi Filtration Chief Executive Officer Riina Salmimies noted that this marks the beginning of a new chapter in mineral processing and expressed pleasure in partnering with Endomines, a Finnish mining company. The application of the Sofi Alchemist system helps the Pampalo gold mine reduce the loss of valuable metals in the process while supporting the continuous improvement of Endomines' production processes.
