The Counter Current Decantation (CCD) removal project began on 52010 and was completed on 101210. The total constructed volume of the materials removed from these areas was 168,545 ft3. CCD area soils were removed to a nominal level of 60 uR for ALARA purposes. ALARA — Demolition activities were reported on and discussed during daily meetings

Apr 17, 2018· Countercurrent decantation CCD. For hydrometallurgical circuits where the mineral product is already dissolved in an acid solution, the role of the thickener is to remove the solids, while recovering a clear liquid solution with the highest possible concentration of the dissolved mineral.
Counter Current Decantation (CCD) thickener circuits are used to recover soluble metal as pregnant stages required to recover the desired amount of soluble metal. Copper at the Ruashi II plant is leached into solution in Stirred tanks.
The Counter Current Decantation (CCD) thickener circuit at Swakop Uranium's Husab project demonstrates the potential of an FL package solution. Designed and supplied by FL, this CCD circuit has the largest diameter thickeners of its kind to be installed on the African continent in this type of application.

designed to treat high grade gold/silver ore using counter current decantation (CCD) ... of the process performance especially with high clay feed at mill start up. ... CCD circuits have traditionally utilised conventional or high rate thickeners.
The new paste thickener provides ease of operation and reliability for applications requiring a high degree of dewatering, such as minerals tailings, mine backfill, and preleach and counter current decantation circuits, according to the company.
Aug 28, 2014· Hydrometallurgical plants often have multiple thickener operations countercurrent decantation. Taking a desired % operating time with a total of 5 thickeners in series in the flowsheet means that each thickener has to be performing as specified % of the time ignoring all other causes of downtime and poor operation!
Continuous countercurrent decantation is frequently carried out with thickeners. In this case, differences in elevation between the first and subsequent thickeners are made in .
A bypass line will be provided to pump slurry directly from thickening to acidulation, where acidic solution recovered from the pressure oxidation (POX) countercurrent decantation (CCD) wash circuit will be mixed with the concentrate with the aim of consuming 85% to of the carbonate gangue component of the concentrate.

Finnish mineralprocessing tech company Outotec has made mechanical and process control improvements to its paste thickener system, designed for applications that require efficient dewatering, including tailings, mine backfill, and preleach and countercurrent decantation (CCD) circuits
The leach residue is washed with water in a series of countercurrent decantation (CCD) thickeners. The washed and thickened leach residue slurry is neutralized by addition of limestone and lime to adjust the pH, blended with the iron hydroxide and gypsum residue from the downstream process, and then piped to a residue holding pond (Sandy Pond) for longterm storage.
Counter Current Decantation Design Formula. The principle of Counter Current Decantation is simply that, when water or solution is to act upon solids, both are made to pass, in contact, in opposite directions, so that at each end the strongest or most potent portion of either is acting upon the weakest or most exhausted portion of the other.
