Ore thickener density measurementVEGA

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.


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


Beginners guide to thickenersMetso

Jun 16, 2017· Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid.


Different Thickening Process In Iron Ore

Different minerals may adopt different concentrating methods. After the iron ore concentrating stage, The limonite ore beneficiation process includes limonite ore crushing, magnetic separation and flotation. After first thickening, low iron content


How a Thickener Works

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 was decanted, the settled solids were

Most common problems in thickener operations (part 1)

These problems are classified according to whether they are caused by thickener design errors, changes in ore properties, or mechanical and maintenance issues. Thickener design errors; In thickener design, there are two specifications that will define the tank efficiency to process minerals: thickener area and


Mineral processingWikipedia

The particles pass over the screen while the water passes through the apertures in the screen. This process is only viable for coarse ores that have a close size distribution as the apertures can allow small particles to pass through. Sedimentation operates by passing water into a large thickener or clarifier.


ThickenersSolid Liquid Separation

The method of operating on a batch process is still practiced in small flow industries but its shortcomings are obvious so once the plants grew larger the need for continuous operation became inevitable. The trend in this direction started at the late 19th century when heavy duty applications such as iron ore taconites, hematite, coal, aluminum

Jul 16, 2019· Feeds with entrained air are a challenge to the thickener flocculation process. Aerated thickener feed that makes its way into the body of the thickener tends to carry fine particles to the thickener surface to form froth. This froth causes issues such as the loss of product to thickener overflows (on product thickeners as was the case with
