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.
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 high-rate primary thickener was inadequate to produce slurry densities required for the desired water reclamation.
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.
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.

Apr 27, 2019· The thickener is applicable to concentrate and tailings dewatering treatment in the mining companies, widely used in metallurgy, chemical industry, coal, non-metallic mineral processing plant ...
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 ...
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 high-rate 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 .

plant and/or full-scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.
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.
The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not.
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.
The thickener allows the solids to settle and produces a clarified water stream which can be recycled back to the plant. Polymer is used in the thickener to facilitate large floc formation and increase effluent quality. Thickener underflow has traditionally been sent to an impoundment or tailings pond. Paste Thickener
How a Thickener Works. ... This probably is the reason why thickening rates in the cyanide plant are sometimes appreciably reduced when an ore is being milled which has partially oxidized in the mine and consequently contains appreciable amounts of reducing salts. ...

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.
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 slurry.It is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.
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.
Feb 12, 2008· The plant, due for commissioning later this year, comprises a six stage (CCD) type high rate thickener circuit, a high density pre-leach thickener, pregnant liquor clarifier and associated settler/clarifiers. This brings the total supply portion of thickeners to ten.
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 ...
