Jan 12, 2017 Thickeners are mechanically continuous process equipment which operates on a particle/floccule sedimentation principle where in simplest terms the solids settle to the bottom of the thickener tank and the water overflows the tank. mineral processing technologies, technical marketing management and. Chat.
The diameter is 3 to 100 m and the depth is 2 to 4 m. The mineral thickener is a center drive thickener, which is traditional thickening equipment with a history of the earlier appliion. The mineral tailing thickener with a diameter of less than 12m is of manual handle type, and thickeners with a diameter over 12m adopt electric handle devices.
Corrections. In Table I of the July article, "improve Clarifier and Thickener Design and Operation," by Joel Christian (pp. 5056), the titles Vi and TSS are reversed. The first TSS is and the first Vi is In the overloaded case on p. 55, the underflow c oncentration should be 240 kg/m 3, not 140.
Thickener can be divided into ordinary thickener tilted plate thickener and deep cone thickener. Among them ordinary thickener is the common equipment in mineral processing plant. The biggest specific of ordinary thickener is simple structure and easy to operate.
The thickener process is one of the staple elements of a largescale minerals processing operation. Thickeners are used to increase the percentage of particle solids in the tailings to maximize water recovery for reuse. The need to efficiently recover water in minerals processing is a priority because
03/07/2015 · Thickener is a kind of dehydrating machine, commonly used for the thickening of concentration or the dewatering of tailings before filtering,also for the work of thickening and purifiion of the solid slurry in coal industry,chemical industry,building materials and water source sewage treatment industry.. In the work of dewatering of tailings, thickener plays an important role in making .
Thickener technology for mineral processing CSIROpedia. ... The aim is to produce a high proportion of particle free liquid called the overflow and small proportion of a thick, mineral rich slurry called the underflow. Contact Me. Global Minerals Thickening Agents Market 2020 Top Leading .
1. Introduction. The gravity thickener, in which particles settle under gravity to achieve solidliquid separation, has been widely used in many industries, such as wastewater treatment, metallurgy plants, and mineral processing [,,,,,,,, ].In mineral processing, a gravity thickener is often used to concentrate tailings slurry due to its large capacity and ease of operation.
Understanding slurry means designing the process to suit the properties of the slurry. Water Recovery: Water Conditioning. Thickener Control: DeSliming: ... We have developed our own unique test and design methods for providing dewatering and mineral separation process solutions;
settle, the process of thickening begins. Thickening and slimes disposal Thickening or gravity sedimentation is the most widely applied dewatering technique in mineral processing. Relative to other dewatering processes, thickening is costeffective and a high capacity process (Wills, 2007). Another
To maximize water reuse, the Khumani plant contracted with WesTech Engineering, LLC to design and implement a twostage tailings thickening process. The first stage consists of two primary highrate traction slurry thickeners, each 295 feet in diameter, situated at the main plant. The first was installed in 2008, with the opening of the mine.
Mineral Technologies carried out the mineral processing test work and developed the flow sheets for a mineral sands project in the Murray Basin, Australia. ... The material is withdrawn using slurry pumps to feed to the spiral ... The bin overflow water containing the slimes reports to the thickener.
Mineral sands slimes; Metal precipitates; Vane Feedwell™ Feedwells are a significant factor in thickener performance. The cuttingedge design of the Vane Feedwell™ marks the first major innovation in the thickening and clarifying industry since the early 1990s. One of the main design features is the interconnected upper and lower zones.

27/12/2017 · Thickener belongs to dehydration equipment, commonly used for the thickening of ore concentrate and the dewatering of the tailings before filtration, as well as the thickening and purifiion of a liquid containing solid particles in the chemical industry, building materials, and water source sewage treatment industry.. In the processing of dewatering tailings, thickening is mainly used to ...
cost, provided that the slurry is not too viscous. For a new system, a smaller pump and pipeline can result in lower capital costs and a marginally higher energy cost, if the optimum density is selected. Keywords: tailings, paste, pumping, slurry Figure 1. The thickening continuum: flow behaviour versus solids concentration

YX Thickening Filtering equipment. Thickener dewatering tailings solid slurry concentration. The thickener is a continuous working concentration and clarifiion equipment, which is mainly used for dewatering of fine and tailings slurry in wet beneficiation operation, and is also widely used for the concentration of solid slurry in coal, steel, chemical, building materials, water source ...
mineral gravity slurry thickener . Thickener Mineral Processing. To start with, mineral thickener works on the principle of Gravity sedimentation and the most common construction of a thickener would be of iron or steel. The continuous thickener consists of a cylindrical tank.
Additionally, the selection of an adequate safety factor that represents the variability of the mineral to be processed must be considered. The safety factor can vary between and Drive torque. The rake drive mechanism has to apply a sufficient force for the rakes to move the slurry in the thickener.
The role of ore properties in thickening process 787 ) d) e) g) rse Fig. 2. XRD patterns of (a) feed (b) slime (c) middling (d) coarse samples Results and discussions Since the amount of flocculant consumption for the thickening process is usually between 20 and 40 g/Mg, the tests were carried out with a wider range of dosage
thickener. Thickeners are used in the mineral processing industry to recover water (to the overflow) and thickened slurry (to the underflow). The customer's thickener was constructed in 2011 with the tank manufactured from concrete. The design was that of a centre column with a half span bridge. The bridge was supported on one end at the
Extracted minerals are fed to the thickener as a slurry via a trough. The solids are settled out into the bottom of the tank, in a process accelerated through the addition of flocculants. Precise density measurement of the slurry underflow is necessary for effective control of the ore thickener.
