  • Tailingsfo Thickened Tailings Storage A discussion
    IntroductionHistoryDiscussionThickened tailings, as the name suggests, involves the mechanical process of dewatering low solids concentrated slurry (Fourie 2003). This is normally achieved by using compression (or high rate) thickeners or a combination of thickeners and filter presses. High Density Thickened Tailings (HDTT) are defined as tailings that have been significantly dewatered to a point where they will form a homogeneous non-segregated mass when deposited from the end of a pipe (Welch 2003). They are not to be...

    Beginners Guide to Thickeners; Beginners Guide to Thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in

    “The plant generates around 10 Mt of tailings a year and, thanks to the Outotec ACT Thickener Optimizer, the paste thickeners can consistently run with a high and stable underflow solids content of 66-68%, regardless of challenging mineralogy and tailings feed-rate variation. This results in average beach slope angles of 3.5° (6.1%) in the

  • Tailings Wikipedia

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

As the Cuajone tailings are known for their difficult

  • High density slurry and paste tailings, transport systems

    High density tailings systems require specialized thickening equipment, normally with increased physical height to allow the formation of a deeper mud bed depth and to increase mud bed retention time. High rake torque is produced by the deep viscous mud bed, and heavy duty rake structures and drive mechanisms are required. Underflow density control Whether the motivation is water savings or

  • Paper: High density paste thickener in Siberia

    Thickened tailings technology was selected in part because the unique terrain made conventional slurry deposition difficult and expensive. The high density thickener design was chosen because of the large diameter necessary to accommodate the solids feed rate while producing a non-settling underflow (paste). An elevated tank, as opposed to on

  • Conventional Thickeners Solid Liquid Separation

    Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away. Likewise, thickeners are often used for storage to facilitate the continuous feeding of downstream filters

  • Design Considerations for a Tailings Disposal System E & MJ

    A high density thickener produces thickened tailings. The difference between a high rate and a high density thickener is the underflow will not segregate—that water remains bound into the mixture. A deep cone, or deep bed, thickener produces paste. Both high density and deep cone thickeners depend on retention time rather than area. Yield


    Work is presently underway to design a thickening circuit capable of delivering the high density tailings to the deposition site. Due to the anticipated difficulty of pumping the HDT it is proposed that final thickening will be carried out within the TSF and the water recovered from the thickener will be pumped back to the processing
