The deep cone thickener shown in Figure 1.5 is again broadly similar in form to a conventional thickener, but the sides of the inverted cone have a much steeper angle, in the region of 37°.
The drive head rotates a low-profile raking mechanism effortlessly inside the thickener, moving the settled solids towards the discharge cone while also increasing solids density.
Therefore, it is important to find a rapid way to dewater and thicken whole-tailings with ultrafine particles for the whole-tailings paste preparation [2]. Study on the flocculation and settling of whole-tailings in deep-cone thickener is particularly urgent.

Deep cone thickener also called paste thickener is higher than other thickeners which consists of deep cone, feeding device, stirring device, control box, reagents adding device, automatic control system, etc.
A proposal of different dewatering techniques applied in the fine tailings produced after final desliming phase, obtained from the treating of phosphatic ores, is the main objective of this work. The dewatering techniques evaluated were column thickener, deep cone classifier, and hyperbaric filtration.
To improve the filling efficiency and ensure mining safety, these stable thickening underflow, flocculation mechanism, dewatering behaviour, and its regulatory methods brought about by this complex deep cone thickener (DCT) are the central issue that this paper needs to focus on the reviewing, exploring and understanding.
The sludge height and underflow rate are the two most important parameters for deep cone thickeners. Therefore, studying the law of change of the underflow concentration with sludge height is important. Discontinuous or continuous dynamic compaction processes of the tailings were investigated physically by using a small, self-made deep cone …
The original concept of the "deep cone" type thickener was developed in the 1960's using a steep floor slope and increased bed volume to produce high underflow densities. Over the years, this thickening technology has evolved and refined to consistently produce non-settling, non-segregating underflow.
