Historically these pipelines were designed to operate at low solids concentrations, however as dewatering technology improved and solids concentrations increased, residue disposal systems have become significantly more complex. Designing an effective

Tailings Management With Paste Thickening

Recovering water from a tailing stream and using it again upstream in the plant reduces the amount of fresh water a mine needs. The cost of water is frequently one of the primary drivers for implementing a thickened or paste tailings disposal system. Stacking.
