Continuous thickeners have undergone several modifications that have resulted from the development of a wide variety of organic polymeric flocculants. As a result, there are now two basic types of continuous thickeners: Conventional and Highrate. Conventional Thickeners These thickeners differ in .
Demo Plant – A demo plant is usually a full scale thickener installed at an existing mining operation and run in parallel to the existing thickening trains. The demo plant could be a deep cone thickener producing high density tailings that discharges into the same delivery system as the already installed conventional thickeners (thus allowing ...
【Description】 The thickener is applicable to concentrate and tailings dewatering treatment in the mining application, widely used in metallurgy, chemical industry, coal, nonmetallic mineral processing plant, environmental protection and other industries. In fact, the highefficiency mining thickener is not a gravity separation equipment, but a piece of dewatering equipment combined with ...
A thickener/clarifier drive unit supplies the torque to rotate the rake arms through the thick sludge. The drive is usually made of cast iron because of its durability. Usage Examples Thickeners and clarifiers are often used in water and wastewater treatment plants to .
Simon Courtenay, product manager for the Outotec 2nd Generation Paste Thickener, said: "The plant generates around 10 million tonnes 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 6668%, regardless of challenging mineralogy and tailings feedrate variation.
Thickeners. Thickeners are used for dewatering slurries of either tailings or product. A thickener is a large circular tank that is used to settle out the solid material from the water in the feed is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.
These thickeners recover approximately 90 percent of the slurry water by volume. Most mining facilities would then deposit the tailings slurry direct into a tailings pond at about 40 percent to 50 percent solids. But this highrate primary thickener was inadequate to produce slurry densities required for the desired water reclamation.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

May 01, 2015· These thickeners recover approximately 90 percent of the slurry water by volume. Most mining facilities would then deposit the tailings slurry direct into a tailings pond at about 40 percent to 50 percent solids. But this highrate primary thickener was inadequate to produce slurry densities required for the desired water reclamation.
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in .
The technology of the Outotec Thickened Tailings and Paste Plant is a novel way to handle and store tailings from various processes like mine concentrators and other processes that produce tailings. As a result, the plant reduces the footprint and environmental risks of your tailings storage facility.
The benefits of Thickeners can vary from user to user depending on the producer''s needs and the industry. For instance, Thickeners can be used in locations where water is in short supply or very expensive, providing immediately reusable process water back to the plant.
The mineral tailing mining thickener consists of cone thickener and harrow scrapping machine, the solid particles suspend in thickener settling by gravity, the pulp in the upper turn into clean water, so that the separation can be realized.
A flowsheet, showing the Carbon In Leach (CIL) process This circuit utilizes a thickener, to maintain a constant percent solids in the ore feed, necessitating less water used in the process, smaller tanks and a smaller pond. It also gives much more control over the process that a conventional CIL plant without a thickener.
May 30, 2013· How thickeners fucntion – Mine provides mining, gold . Thickeners, how they work . A thickener is a machine. Optimised thickeners in coal preparation plants | PACE. Using optimised thickeners for level measurement applications in a coal mine can yield safer and more efficient plant control, writes Marie Osterskog.
Delkor recently achieved mechanical completion of seven thickeners, a flocculation system, and a pinned bed clarifier (PBC), a unit used for hydrometallurgical plants where solution clarity is important, at a Moroccan silver leaching plant. The thickeners will form part of the plant''s counter current decantation (CCD) circuit, which helps ...
automated control of the plant. All mining concentrators and coal preparation plants have tailings thickeners. These instruments treat the process water by removing suspended solids and then returning the water back to the concentrator or coal prep plant. They then pump the solids to a tailings dam.
Apr 27, 2019· The thickener is applicable to concentrate and tailings dewatering treatment in the mining companies, widely used in metallurgy, chemical industry, coal, nonmetallic mineral processing plant ...

Likewise, thickeners are often used for storage to facilitate the continuous feeding of downstream filters or centrifuges. Historically thickeners were introduced to the mining industry in 1905 when the beneficiation of ores by froth flotation was invented in Australia.
Thickener is of great significance for the dressing plant, so a better understanding of influential factors about thickener capacity should be made. The unit capacity of the thickener refers to each unit concentrated area of thickener, and tons of material processed per day and night. The main factors influencing production capacity are as ...
Feb 12, 2008· The plant, due for commissioning later this year, comprises a six stage (CCD) type high rate thickener circuit, a high density preleach thickener, pregnant liquor clarifier and associated settler/clarifiers. This brings the total supply portion of thickeners to ten.
