Thickeners or thickener plants OutotecThickeners are recognized as one of the more costeffective technologies for recovering water from tailings streams. Significant energy savings can be achieved by maximizing the recovery of water close to the mill. In addition, a higher density of tailings deposited in the dam tends to reduce the footprint and produce a more stable tailings deposit. Figure 1. Outotec Paste Thickener. When considering a thickened tailings solution, there is the question of whether the technology to thicken tailings should be located in the thickener as a piece of equipment, or whether a complete solution is required to achieve the best performance. We typically view the components required to thicken tailings in isolation rather than considering them as a complete plant comprising a thickener, pumping system, automation systems, and the necessary ancillary equipment or systems required for operation (see Figure 2). Because all these components interact with one another, in order to identify how perfo

Despite the design of the thickener and installation of good instrumentation, poor overall plant design, inadequate automation, or low operator focus can be contributing factors in thickeners that fail to consistently achieve the best results. Although the duty of a tailings thickener can be defined in quite simple terms, the thickener will experience a wide range of operational conditions during its lifespan. Mining operations will experience changes in the geology of the mine that lead to variable ore gradesthe mass flow of solids will vary according to the milling ratesthe concentration of solids in the feed will vary because of operational issuesand the setting rate will depend on the mineralogy and particle size. This variability needs to be compensated by the control systems and ancillaries surrounding the thickener. Improvements can be achieved by adjusting the plants flow sheet to suit the overall system objectives, and significant energy savings can be realized by op

The benefits of good plant design are not limited to new thickener installations. Tailings dams in existing plants fill faster than is optimal, and often the technologies available when the dam was planned have evolved, providing opportunities to improve thickener performance. These improvements lead to the opportunity to improve the performance of the plant by increasing water recovery or changing the deposition characteristics of the thickened tailings. Simply upgrading the thickener to incorporate new and improved components may not lead to the plant achieving its maximum potential. By understanding the rheological properties that have an impact on the thickening and disposal methodology it is possible to realize significant improvements in TSF costs. These changes introduce all of the complexities of a new thickener installation, and consequently the entire system should be evaluated and improved as necessary.

In order to improve the performance of a thickened tailings plant, the best approach is to identify and examine the variables that are limiting its performance. The objective of thickening is to recover water from the tailings and to produce a slurry that will optimize the costs of the tailings storage facility. Often the tailings system is operated by several departments, with the benefits of good performance being felt in different departments to the ones that have to bear the costs, leading to poor optimization. Pumping, or slurry transport, is the link between thickening and the tailings storage facility, and this function is often the ratelimiting variable in a tailings system. Higher densities increase the pumping pressure required or limit the flow of gravity systems and can require expensive infrastructure to operate at higher water recoveries. The training and focus of operators can also be an important limiting factor in terms of thickener performance. The adjustable vari

Advances in thickener design have improved the degree of separation possible from tailings streams, however limiting the selection criteria to just the thickener can constrain the operation potential. Integrating ancillaries, automation and operator training with the equipment can improve operational outcomes and decrease operating costs. By focusing on water, looking at the true costs involved and the implications of water quality on plant performance, better outcomes and safer tailings storage can be achieved.

Tailings Thickened Tailings Storage A discussionThickened 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 nonsegregated mass when deposited from the end of a pipe (Welch 2003). They are not to be confused with paste tailings which are a higher (and more expensive) degree of thickening to produce very dense slurry that is often pumped to its final storage facility using positive displacement pumps (however, centrifugal pumps can be used to pump paste where the tailings properties are favourable). HDTT is often defined in industry where the tailings have a high yield stress (typically higher than 20 Pa but no higher than 100 Pa), do not require deep cone or paste thickening technology, ble

In 1973 the Falconbridge owned Kidd Creek Metallurgy Plant in the town of Timmins, Ontario, Canada was the first site to utilise surface thickened disposal of tailings (Engels and DixonHardy 2004). The conventional storage facility was converted to HDTT to eliminate further raising of the traditional retaining embankments that were situated on very soft and sensitive clay foundations (ICOLD and UNEP 2001). The tailings are discharged from spigots on a central ramp that is currently 20m high. At the base of this ramp is the 32 m diameter, high compression thickener that produces a slurry density of 60 65% solids (Golder 2005).

Operating costs are higher for thickened disposal due to the associated dewatering costs. However, there are significant advantages to thickening tailings. Perhaps the most important is that higher volumes of water can be recovered and the seepage and evaporation losses from the tailings storage facility can therefore be minimised. Sustainable water use in the mining industry is becoming increasingly more important (Welch 2003). The potential for recovering high volumes of water at the plant (by the thickeners) eliminates the losses associated with the transport and storage of water either at the tailings facility or in holding ponds (Fourie 2003). Environmental problems such as seepage, spillage of process water and the potential for water to act as a transporter for tailings flows (e.g. embankment breach) is significantly reduced. Some other main advantages to thickening tailings are: 1. No large starter dam is required which significantly reduces capital cost. 2. Reclamation cost
