How to Operate a Thickener 911 Metallurgist
Apr 25, 2016 The solids go from the bottom of one thickener to the top of the next; the solution overflows from one thickener to the next, but in the opposite direction to the way the pulp is travelling. As the solids go up the line, more and more gold-bearing solution
How a Thickener Works Metallurgist & Mineral Processing
Jul 13, 2016 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
Advanced thickener control TON Outotec
Jun 13, 2017 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

Processing Nickel Ores
The nickel settles and the solution is pumped out to a holding tank. Since the solution still contains some nickel,it is re-processed again to recover the remaining nickel. The nickel can then be removed through a cone bottomed tank or by a thickener/filter operation to yield the nickel powder.
In A Nickel Processing Plant, Ore Received From Th
In a Nickel processing plant, ore received from the mine consist of not only Nickel, but other elements such as Cobalt, Copper, Iron, etc. All these elements need to be separated from the ore as desired and undesired products. into a thickener (i.e., a solid-liquid separator) where the solid are separated from the liquid by sedimentation

Tailings
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed..
