Eriez CavTube at CRU Phosphates+Potash 2026: ultrafines recovery notes for plant engineers
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Eriez will showcase its CavTube column flotation system at CRU Phosphates+Potash 2026, focusing on recovering ultrafine phosphates and potash from tailings streams to improve overall plant performance and water reuse. Global Product Manager – Column Flotation, Michele Tuchscherer, will present a technical paper on “Sustainable Slimes Beneficiation”, detailing how column flotation can treat slimes fractions that are typically lost to tailings. For process engineers, the pitch centres on higher ultrafines recovery, reduced tailings volumes and more efficient reagent and water utilisation in existing circuits.
Technical Brief
- For similar fine-tailings circuits, column flotation can defer new tailings storage construction by improving recovery.
Our Take
Eriez appears several times in our mining product coverage, including its 2026 CONEXPO-CON/AGG showcase, signalling a deliberate push to position the company as a full flowsheet solutions vendor rather than just a niche equipment supplier.
For phosphates and potash operations, column flotation aimed at ultrafines recovery has strategic implications for tailings management and water use, which aligns with the ‘Sustainability’ tag and may help operators defer greenfield expansions by squeezing more value from existing ore streams.
