Manufacturer Brochure Information

There is a range of underflow densities that are non-Newtonian suspensions. The WesTech HiDensity™ paste thickener produces non-settling and non-segregating underflow with low yield stress. There are many installations where site-specific objectives are best served with a lower yield stress underflow. The HiDensityTM paste thickener is designed for these applications.

Producing lower yield stress underflow has many advantages while still providing the non-settling, non-segregating, and rapid drying characteristics of paste/thickened tailings. These advantages can translate into significant reductions in both capital expenditure and operational cost for a tailings disposal system:

  • Very large tonnage may be processed in a single thickener
  • Reduced underflow pumping cost
  • Improved surface stack management
