gold plants use conventional thickening with flocculant addition. High rate thickeners, as well as de-watering systems that use cyclones only or cyclones and high-rate thickeners can also be used in principle. Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching

building, with the exception of the large, 215-foot diameter pre-leach thickener located on the north side of the mill building. As noted above, the paste plants are located within separate buildings and each plant has a thickener tank located outside. The Williams paste plant building and thickener tank are located
A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the bed a slope towards the centre of the thickener.
Hello there, am interning at a gold mine where there are problems with the clarity of the overflow of the pre-leach thickeners. Initially, only flocc was used at 0.1% strength. Now we are testing a coagulant as well at different dilutions on the plant. The clarity has improved over the 2 weeks w
Pre-Leach Thickener: Ensures consistent densities through the leach circuit during cyanide addition resulting in increased leaching efficiency. Completed and commissioned 3November. Leach Tank: Additional leach tank, for a total of seven tanks, increases residency time by two to three hours.
