Tailings & Water Management | McLanahan

Thickeners Thickeners allow producers to recover and immediately reuse their process water. They are beneficial to producers in a variety of industries, as well as for sites where a lack or cost of water is a concern. Thickeners can drastically reduce the size of settling ponds, or when paired with a dewatering device, eliminate them all together.

Thickener Optimisation in mineral processing | FMDRCZ

The rule of the thumb is: The higher the density, the less process water is pumped out of the thickener's underflow. Thus, through the optimisation of water content in the underflow, recycling of process water can be maximised, while ensuring that the underflow slurry is sufficiently liquid to be managed by the underflow pump.
