Optimum countercurrent decantation (CCD) relies on two key functions: 1. Maximizing wash water contact with the incoming slurry
Dorr Thickener. The mechanics of the decantation system is of the simplest, but is worthy of study nonetheless. The Dorr thickener is universally used for

In the operation of continuous countercurrent décantation it is well known that an increase in the number of thickeners results in an increase of the fixed costs. But
The counter current decantation had been used since 90 years ago in the hydrometallurgical plant. It is currently adopted by all new hydrometallurgical plants located in the Katanga Province of
The Counter Current Decantation (CCD) model is used in ProBal mode to quickly determine the concentration in the final over and under flow streams from a
The overflow from the first thickener of the Counter Current Decantation series containing the greatest amount of dissolved metal is sent to precipitation or to the grinding and classifying circuit. The underflow is
Fruitful counter current decantation leach circuit design uses the latest feedwell design and particle settling techniques for maximum efficiency. The ability to create a high thickener underflow density can allow for less stages in the circuit, reducing costs. At Fruitful, we have developed gamechanging technology that creates a high
Abstract: Kinross Gold’s Kupol Mine elected to use deep cone thickeners for their countercurrent decantation (CCD) circuit as well as the grind thickener. Deep cone thickeners are commonly used for CCD circuits in the
The process used for the washing of the copper leach solution from the copper ore is a Counter Current Decantation process with Thickeners supplied by FL Schimdth. CCD thickener circuits are used to recover soluble metal, Pregnant Liquor Solution (PLS), from ore leached residue.
Typical Applications. Counter Current Decantation (CCD) Tailings; Pre and postleaching duties; Mineral sands slimes; Clay duties; Reactorwell™ Reactorwell™ is a part of HCT. It's a firstclass feed system that maximizes thickener performance while minimizing flocculant consumption and bringing significant cost efficiencies to your operations.
In the operation of continuous countercurrent décantation it is well known that an increase in the number of thickeners results in an increase of the fixed costs. But inversely it happens that the variable costs are reduced, i.e. the valuable material has a better recovery. The aim of this paper is to solve the problem by means of an economic
A thickener at WMC Resources' operation in Western Australia. Flocculation in thickener feedwells is used for: Treating tailings; Preconcentrating ore before leaching and digestion; Giving countercurrent decantation washing in trains of two to 10 units; Thickening concentrate products
Fruitful says it has delivered a thickener solution to help double production rates at one of the world’s largest copper and cobalt producers in the Democratic Republic of the Congo (DRC). “This solution included six counter current decantation (CCD) thickeners and one preleach thickener, each measuring 31 m in diameter.”

The aqueous beryllium sulfate is separated from the solids by countercurrent decantation thickener operations. A beryllium concentrate is produced by a countercurrent solvent extraction process (Maddox and Foos 1966). This concentrate is stripped of its beryllium content with aqueous ammonium carbonate. By heating to 70 °C, aluminum and iron

The Rössing Uranium countercurrent decantation (CCD) circuit is scheduled to process ore with a high calc index from to . This material was found to be associated with poor settling performance in the CCD circuit. In order to quantify the root causes of the poor performance, benchscale test work was conducted on the thickener feed.
The workhorses behind this technology is the paste thickener. The increased underflow solids content that a paste thickener can achieve can create real benefits for several applications, including the counter current decantation (CCD) circuit, mine backfill, autoclave feed and surface tailings disposal impoundments.
