Almonty–Wolfram Los Santos tailings deal: key process notes for mine engineers

30 Second Briefing
Almonty Industries has signed a long-term tungsten concentrate supply agreement with Sandvik subsidiary Wolfram Bergbau und Hütten AG for retreatment of the existing tailings stockpile at the Los Santos Mine in western Spain. The contract covers a minimum of about 1,720 t of contained WO₃ recovered from historical tailings, shifting the operation from primary ore mining to secondary extraction. For process engineers and tailings specialists, the deal signals continued commercial appetite for reprocessing fine-grained tungsten residues where grades and volumes justify dedicated retreatment circuits.
Technical Brief
- For similar brownfield tungsten sites, such offtakes can justify regrind, flotation and fine-particle recovery upgrades.
Our Take
Almonty Industries now has long-term tungsten offtakes both from Sangdong in South Korea and from tailings at Los Santos in Spain, which in our database signals a deliberate move to de‑risk price and volume exposure ahead of its large capex programme funded via the US$700 million convertible notes issue reported in June 2026.
Supplying retreated tailings from Los Santos into Wolfram Bergbau und Hütten AG’s European processing chain aligns with the EU’s critical raw materials agenda noted in our related coverage, and is likely to strengthen Almonty’s positioning with European policymakers as a recycler as well as a primary tungsten producer.
