Treatment of Gold Tailings in High Rate Thickeners
Since most CIP tailings pulps are at a density of about 40% solids, it is necessary to dilute them in order to achieve good flocculation in the thickener feedwell. In the above example, a capital cost of $54,000 and power cost of $32,000 p.a. was incurred by the installation of overflow recirculation pumps, piping and instruments.

Sizing a high rate thickener
To my mind in a high rate thickener, solids concentration during flocculation is a powerful tool and we have to choose the solids concentration to achieve maximum flux concentration. In this condition selecting a safety factor would led to overcome variation in feed properties (e.g. solids concentration) and a wise design would be achieved. ...
Beginners guide to thickeners
By adding depth and torque to a high-rate design, high-density thickeners improve underflow densities at a substantially lower cost than deep cone thickeners.

DEWATERING * CONVENTIONAL AND HIGH-RATE THICKENERS
High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.

Beginners guide to thickeners
In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.

Raking Maximizes Performance in Thickeners and Clarifiers
Raking plays a major role in transporting solids to the underflow discharge point and increasing the solids concentration in a thickener or clarifier. The main purpose of a thickener or clarifier is to separate solids from liquids. A thickener achieves this goal by stimulating the release of as much liquid as possible from solids in the underflow.
