Diefenbach thickeners are comprised of a tank, feed pipe feedwell, rake (and pickets, depending on the thickener style), a bridge containing the rake drive mechanism, and a chemical dosing system. The slurry feed enters the thickener from a de-aeration tank and into the feedwell. Chemicals are added to the feed to aid in rapid settling of the ...

Place a measured quantity of pulp at a known density in a beaker or glass cylinder. Fix a narrow strip of paper on one side of the container. Mix pulp thoroughly. Draw a line on the paper at the top of the pulp and mark "0" minutes. For five minutes, at one-min­ute intervals, mark the point to which the solids have settled.

Most of the world's minerals pass through solid-liquid separation in a thickener at some point in their processing. Thickeners are used to either: concentrate mineral slurries prior to extraction of …

Thickeners in mineral processing can be monitored and improved by measuring density in the feed of the system, in the feedwell and in the underflow. Combined with a flow …

Clarifiers are characterized by having larger diameter, shallow tanks with a more lightweight rake and drive system. How to size a clarifier. A starting point for sizing clarifiers for most sand and mineral processing applications is to take the volumetric overflow divided by settling area, often abbreviated to m/hr or gpm/ft2.

Over the years, nomenclature has been adopted that is specific to thickener functions in the mineral processing industries. The solid-liquid mixture that is to be separated by sedimentation is known as …

The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants. The inlet stream going to a thickener generally is called 'feed' or 'influent'. Overflow from the unit may be called 'overflow', 'effluent', or 'supernatant'.

The thickener is applicable to concentrate and tailings dewatering treatment in the mining application, widely used in metallurgy, chemical industry, coal, non-metallic mineral processing plant, environmental protection, and other industries. In fact, the high-efficiency mining thickener is not a gravity separation equipment, but a piece of ...

The thickener is mainly used for the dehydration of concentrate, medium ore, and tailings slurry in wet beneficiation. Widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection, and other industries.

Our thickener could be used for gold mining, lead and zinc mining, copper mining, etc. Advantages of ZJH minerals' thickener. 1. Equipped with automatic adding device of flocculant. The dosage of powder flocculant can be automatically adjusted by inputting the daily processing capacity and density of the thickener on the touch screen. 2.

In mineral processing plants, thickening is intended to remove the water content of pulp so that the mineral processing products meet the requirements of the other processes. Usually the solid mass fractions of concentrate and tailings are 30–40% and 8–20%, respectively. After thickening, the solid mass fraction of concentrate can be 65 ...

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 …

A mining mixing tank, or a blending or agitation tank, is a container used in the mineral processing industry to mix various components, such as ore, chemicals, and water, to create a homogeneous slurry.This slurry is crucial in many mining processes, including leaching, precipitation, flotation, and hydrometallurgical processes. The tank facilitates …
