Improve Mine Productivity and Reduce Environmental Impact

Thickening and Paste Backfill

Inevitably, underground mining creates cavities in the earth. Paste thickening is an attractive alternative to conventional tailings management solutions, especially as it applies to backfill. The paste backfill process can dispose sludge and/or tailings that may contain hazardous materials and reduce environmental impacts on the surface.

Shallow mines and long-distance runs can incur exorbitant pumping costs. In these operation scenarios, high-yield stress paste makes a better choice for backfill. Beyond that, paste thickening can maximize water recovery, maximize underflow density, and reduce paste slump.
