Mining Application
Thickener Underflow Isolation
Manage abrasive, high solids content slurries while separating tailings from reclaimed water.
Maximize Water Reclamation With Reliable Underflow Isolation
Thickeners are designed to separate processed solids for recirculation and reprocessing, or for distribution to tailings. In the thickener unit, valuable water is extracted from the slurry to reuse in other parts of the mining operation. The remaining solids material becomes concentrated for more efficient transfer to the tailings storage facility (TSF).

Better Magnetic Flow Meter Sensors Increase Productivity
Based on many plant visits and discussions with Emerson customers, I have concluded that handling slurries is one of the biggest problems for operators and reliability teams. The most frequently mentioned issues are clogging and erosion, which certainly take their toll, but there is also a more subtle challenge related to measuring flow. Why slurries …
