Paste backfill Services
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.

Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/or tailings that may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground.
