Thickener underflow at approximately 54 ww solids is pumped to a train of four acidulation tanks Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit Process air is also injected into the acidulation tanks to aid in carbon dioxide removal...

It may also be lodged in the classifier and thickener tanks Especially in a small high grade mill this may be a serious tieup of gold Furthermore coarse gold particles are slow to dissolve in cyanide solution and accordingly there is a possibility that they will be discharged in the mill tailing before being completely dissolved
gold plants use conventional thickening with flocculant addition High rate thickeners as well as dewatering systems that use cyclones only or cyclones and highrate 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
The OVERFLOW or the portion that is being decanted will be sent to a holding tank While the solids will be taken from the bottom of the thickener w filtered and washed to be sure there isn’t any solution left on the rock particles Once that is done the solids then will be discarded as final tails
HiFlo High Rate Thickeners Clarifiers provide rapid liquidsolid separation of high flow rates with optimum flocculation and adapts to process fluctuations HiFlo Thickeners are available in several standard sizes custom configurations including bolttogether tank flat bottom elevated tank rake lift and embeeded stave
In high rate thickener HRT designs the rise rate or solids loading will dictate the required tank diameter for any given throughput In high compression HCT and paste PT applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved
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 flatbottomed tanks into which the pulp was fed until the tank was full The solids were then allowed to settle as long as required the top liquid was decanted the settled solids were
The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same Fundamentally thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids Thickeners are used to concentrate solids while clarifiers are used to purify liquids A thickener will give you a high density underflow while a clarifier will not The
Thickener plant flow sheet Reducing operational variability through control system improvements Despite the design of the thickener and installation of good instrumentation poor overall plant design inadequate automation or low operator focus can be contributing factors in thickeners that fail to consistently achieve the best results
