How pH affects thickener settling rateYou don't mention whether the thickener is for a preleach or tailings appliion. If it is for tailings then the addition of the lime is to my mind wasting money as the process is complete at this time and you are adding another reagent prior to tailings disposal.

Underflow thickener pump problems..Mar 23, 2009 · I was just curious if anyone had a pump model suggestion for the appliion of pumping preleach thickener material. RE: Underflow thickener pump problems.. eboutin (Mechanical) 23 Mar 09 09:20. There have been electrical pumps that have been successful in this kind of service.
Lihir FactsThickener underflow at design of 55% solids is pumped to one of three preoxidation tanks. A portion of the grinding thickener overflow is recycled to the grinding circuit for mill water use, including SAG mill feed dilution, trommel sluice water and recycled feed dilution.
Leaching Sample Clauses | Law InsiderThe thickener underflow, which normally ranges from 50% to 55%, reports into the preaeration tank for precondition prior addition of the cyanide. The preconditioning is performed in order to render cynocides less reactive to cyanide. Cyanide is automatically added to either Leach 2 or Leach 3, depending on the degree of the pre aeration stage.

Rubber Lining | Specialists in Rubber Lining Australia | The rubber lining is performed based on our documented lining system. We can mobilise to your site with as many liners as needed for short term or long term requirements; whether it be for an 8 hour shut down or something more specific such as lining a leach tank, a flotation cell or a thickener.

Mineral Processing SolutionsIn all cases, the ore is milled and classified prior to leaching. Since the final milling is done in a ball or rod mill as a slurry, it is necessary to concentrate the milled ore slurry in a preleach thickener prior to the leaching process in order to reduce dilution.

Major Mines Projects | BatemanThe preleach thickener is fed by the trash screen undersize and the thickening area sump pump. Flocculant is also added to improve the settling rate and lime is added to adjust pH. The thickener overflow feeds by gravity to the process water tank, while the underflow is pumped to the pre aeration tank in the CIL circuit. During shutdown, the ...
Major Mines Projects | Dugbe ProjectAug 14, 2021 · The preleach thickener will produce an underflow product of 45% solids (w/w) as feed to the CIL circuit. Flocculant solution will be added to the thickener to assist with settling of particles. The thickener overflow product gravitates to the process water circuit. Carbon in Leach (CIL) The CIL circuit comprises a series of mechanically ...

Grinding down costsMar 21, 2016 · Switching cyanide injection to the preleach thickener and the leach circuit resulted in less wasted cyanide. A joint research project. The project emerged from discussions among COREM members, which include Canadian Malartic and other domestic gold producers. Finding ways to reduce cyanide consumption is a longstanding shared interest; about ...
Vietti SlurrytecSteadyBed ® Thickener Control System with SonarTXM ® Technology. The SteadyBed ® Thickener Control System controls the thickener discharge rate (underflow pump speed) based on the input parameters: mud bed height, rake torque, rake position and underflow density to produce consistent optimum performance of the thickener. Ideally a thickener should be operated at a mud bed height .
Major Mines Projects | Damang MineThe pre leach thickener overflow joins the process water pond as recycled water. Loaded carbon from the CIL is acid washed and eluted at high pressure and temperature. Gold is finally recovered by electrowinning of the pregnant solution and smelting of the hodes with flux.
