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'.
Cyanidation of gold is a gold extraction method from the gold ore. It has been more than 100 years since the cyanide solution was used to leach gold from ore in 1887. Working Principle: Gold can dissolve in cyanide solution. The chemical reaction process as below: 2Au+4NaCN+O2+2H2O——-2NaAu (CN)2+2NaOH+H2O2. The gold …

3. High-Efficiency Thickener. In addition to the inclined plate installed in the thickener, the high-efficiency thickener has a special flocculant adding mechanism. The diameter of the thickener can be reduced to 1 / 3-1 / 2 of that of the common thickener, and the floor area is only 1 / 9-1 / 4 of that of the common thickener.
The pH scale is used to determine how acidic or basic the water is. Most flocculants work best at neutral conditions (pH 7) while some work independently of the pH. Flocculants are categorized as anionic, nonionic or cationic and therefore affected by pulp pH. Basic thickener operation will have you understand the simple electrics of water.

Gold Ore Roasting Plant. To achieve optimum gold recovery from the certain sulfide ore body, the ore must be finely ground to achieve proper oxidation and mineral separation. The ore is separated into stockpiles after it has been mined. These stockpiles are based on gold content, sulfide content, and carbonate content.
The thickening process, although operated successfully in a large range of sites around the world, is poorly understood and predictive design of thickening devices is still empirical. Although predictive models of thickening do exist, the correlation to reality is often poor and there is a desperate need to bring the two together to make ...

The control of the thickener must accommodate fluctuations in the process stream. This control is achieved by manipulating both the flocculant addition and the rate of underflow pumping. However fluctuations in ore type cause random changes in the required flocculant dosing. With PID loop control the thickener inventory can be controlled ...

Thickeners are often operated to keep the interface height constant using a level control device or manual measurements of the sludge level. In this case, if the feed solids rate is increased from 10.0 to 11.1 metric tons/day, the operating point at steady-state will move from point no. 1 to point no. 4. The underflow pumping rate will have to ...

Thickeners utilize gravity sedimentation to facilitate the separation process. 2. Importance of Thickeners in Mining Operations. Thickeners play a critical role in various stages of mining operations. They are commonly used in the processing of ores to separate solid particles from the process liquids, such as water or chemical solutions.
If, for some reason, the thickener's settling rate is too slow, as in the case of the grind being so fine or you are dealing with clay rich ore and now the concentrate stays in suspension. The thickener could be "sliming" and will produce a dirty overflow combined with a low density underflow. If this is ...

The thickened slurry is drawn from the thickener with one of two 7.5 HP 2.5″ variable speed centrifugal pumps. A selector switch at the MCC will select between the pumps. Gland seal water to each pump must also be shut off or turned on manually at the time of a pump switch over. The speed of the pump is controlled by a density controller.
Mining thickener consists of several key components that work together to facilitate the separation and concentration of solid particles from the ore slurry. Here's a closer look at the main components of a mining thickener: 1. Tank or Basin. The tank or basin serves as the main vessel where the settling of solid particles takes place.
