Paste Thickening & Backfill Mineral Industry Solutions

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.

Design and Characterization of Underground Paste Backfill

The mixture design and optimization of CPB are based on laboratory- and paste plant-scale testing. The uniaxial compressive strength of paste backfill material is universally accepted as one of the most important design parameters. The other design parameters are material characterization, dewatering and rheological properties.

Paste is a homogeneous mixture of solid and bearing fluid, in our case iron slimes and water. The distinct properties are higher yield stress and solid percentage. This means better storage and uniform drying. The dried slimes can be reclaimed and reused or sold to prospective buyers. Entire cycle is of around 15-20 days.

In Brazil, WesTech recently designed thickeners for a bauxite beneficiation facility in a very wet tropical location. The tailings system consisted of two high density paste thickeners that produce a low yield stress paste. This type of paste, which could be pumped with centrifugal pumps, was expected to produce a low angle beach slope.
