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
