Concentrate Dewatering & Thickening
The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...

Gold Extraction Methods From Three Types of Ore
However, extracting gold from quartz vein gold ore is a meticulous process that requires careful planning and execution. 1. Cyanide gold extraction includes crushing, leaching, filtering, adsorption, elution, etc. The first step in the method is crushing the quartz into small pieces. This can be done using a jaw crusher or a mortar and pestle.

Gold Flotation
GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.

Comprehensive Guide to Mining Thickeners | Mining Pedia
These thickeners feature a steep-sided cone-shaped tank, which promotes enhanced settling of solids. The deep cone design allows for a larger settling area and provides improved retention time for effective solids-liquid separation. Deep cone thickeners are commonly used in processes where particle settling rates vary or where …

Thickeners
To illustrate the differences between these thickener types. Figure 18.5 depicts underflow produced by the thickener compared with the relative yield stress of the material. High-rate thickeners produce the lowest density and yield stress (<20 Pa). The highest yield stress underflow is produced by deep-cone thickeners and can reach over …

Thickener
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.

Thickening
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'.

Thickener Safety
The only way any object can be removed from the cone is by shutting down the thickener and emptying it. With a hard hat they tend to enter the cone upside down. This means that they will seal the only place that the thickener can be emptied from. The alternative is to empty the thickener with a pump which is a long slow job.
