Dewatering Equipment - 911Metallurgist

The first step of the dewatering procedure is usually sedimentation. The design engineer must be extremely careful when developing the size of concentrate thickeners from laboratory data. In the laboratory, concentrates settle extremely rapidly. Calculated unit area requirements of less than 0.03 square meters per MTPD (0.3 sq ft per STPD) are common. However, concentrate thickeners in …

Concentrate Thickeners - Hawk Measurement

Concentrate thickeners generally use gravity (no chemical floccing) only to settle out the concentrate particles. Therefore we must use a higher powered 7 crystal arrayed sonar trans-ducer to penetrate the suspended solids to monitor the heavy density bed level. This provides adequate control and monitor- ing for the underflow pump to guarantee a high density bed being pumped to the ...

This is in contrast to low bed applications, such as concentrate thickeners where torque can sometimes be used manually to help indicate inventory. FLOCCULANT MEASUREMENT. On-line measurement of the settling rate of a sample drawn from the feedwell is the fastest way to determine if the flocculant requirements of the feed have changed. An ...

Concentrate Thickener Operation

In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here we discuss Basic Concentrate Thickener Operation. For the mine to get its concentrate to the smelter it will have to be transported, by truck, train or ship. To illustrate ...

Concentrate Dewatering & Thickening

Central Drive Thickeners are made with tanks ranging from 6 to 100 ft. in diameter, but the larger sizes are not as a rule employed for concentrates, the Traction Thickener being preferable for diameters in excess of about 50 ft. Traction Thickeners are made in diameters of 8 to 300 ft. or more, and are commonly used in all sizes for dewatering tailings. The size of a concentrate thickener is ...

DEBOTTLENECKING OF THICKENERS IN A CHANGING …

DEBOTTLENECKING OF THICKENERS IN A CHANGING ENVIRONMENT Abstract Thickeners are utilized in mineral processing for the purpose of solid-liquid separation (dewatering). Thickeners separate an incoming feed slurry (i.e. water with solid particles of either product or tailings material) into two distinct streams; one consisting of clarified water and the second stream being a slurry concentrated ...

Improve Clarifier and Thickener Design and Operation

A design method for thickeners and clarifiers known as the batch flux curve technique was developed over 20 years ago, but still is not well-known in design and operating circles. An informal survey of major clarifier and thickener manufacturers found that none of the firms surveyed use this method for sizing and maximizing operating conditions. Here, we will show the benefits of using this ...

How a Thickener Works - Mineral Processing & Metallurgy

How a Thickener Works. Previous Next Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid ...

reduction is different. Generally thickeners concentrate sludge at lower than 15% concentration, the dewatering units concentrate the sludge to higher than 15% concentration [3]. Thickened sludge still behaves as a liquid and can be pumped. However, the dewatered sludge generally behaves as a solid and can be trucked in most cases.

Reducing mine water requirements - ScienceDirect

Concentrate thickeners and intermediate thickeners or clarifiers are also common within plants and the overflow is available to recycle. Mines with a positive water balance by definition discharge excess water into the local environment. However, some mines with a positive balance may still import raw water onto site for clean water users, such as pump GSW. Due to regulatory requirements, the ...

Thickener VF Deaerater - Outotec

One of two concentrate thickeners at site, this thickener was not performing optimally. It had significantly aerated froth on the thickener surface, resulting in high solids content in the thickener overflow. Additionally, site was also soon to transition to a new orebody, with thickener throughput to increase from the original design of 26 tph to 50 tph. Outotec was awarded the project on an ...

The increase in flocculation efficiency realised in high rate thickeners may increase in a bulk settling rate 2 to 10 times over that obtained in a conventional thickener, thus reducing the unit area requirements by a similar factor. The corresponding volume may be 4 to 15 times smaller than with conventional thickeners in the same application.
