One of the benefits of Thick-It is that it is available in different forms, including powder and pre ...
Diefenbach HR Series Elevated High-Rate Thickeners are a type of industrial liquid-solid separation equipment used for recovering immediately reusable process water or separating waste solids from leach liquor. This type of thickener features a fabricated sag steel floor on larger diameter tanks and provides open access under the tank for more ...
Underflow from the pre-leach thickener will be pumped to the carbon-in-leach (CIL) circuit, which comprises a leach tank and six CIL tanks with carbon for gold adsorption. The loaded carbon will then be transferred to the elution circuit, which will further undergo electro-winning and smelting to produce gold doré. ...

The pre-leach thickener, which was not exposed to corrosive conditions, is constructed from carbon steel. "We also designed and supplied five impurities removal thickeners, which are high rate thickeners, also in LDX2101 stainless steel," Areington says. "The sizes of these units ranged from 20 to 30 m in diameter."
Switching cyanide injection to the pre-leach 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 …
The trash screen underflow slurry is fed to the high rate pre-leach thickener. Diluted flocculant and barren solution are added to the feed of the thickener to assist in solids settling and thickening. Thickener underflow is pumped to the leaching circuit. Overflow pregnant solution containing precious metals dissolved into solution is pumped ...
To determine the correct Thickener for an application, ... the rake lift is programmed to activate once a pre-set drive torque is measured. The drive torque is assumed to have increased due to an increase in the thickness of the mud. By lifting the rake mechanism out the thick mud, the operator can buy some time to address the change in ...

When one of the world's largest copper and cobalt producers wanted to double its production rates, it chose FL to provide a thickener solution that included six of its proven high- density thickeners. This solution, with the order placed in 2020, included six counter current decantation (CCD) thickeners and one pre-leach …
The discussion regarding classification efficiency due to lower feed density is often held as a justification for the installation of a pre-leach thickener. In this case you can run the cyclones at a lower density and increase separation efficiency thus resulting in a finer overflow size distribution.
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 …
