Counter Current Decantation (CCD) thickener circuits are used to recover soluble metal as pregnant liquor solution from ore leach residue. The basis of CCD operation is to concentrate suspended solids thereby minimizing liquor content in underflow slurry that flow in one direction.
Alternative flowsheet options are counter-current decantation (CCD) thickeners or counter current washing (CCW) horizontal belt vacuum filters. Extensive sedimentation and vacuum filtration simulations have been completed by FLSmidth on leach discharge slurries to indentify equipment capacity and performance.

Calculate Countercurrent Washing Efficiency
Charge-Coupled Device (CCD) is a type of semiconductor device that's sensitive to light. CCD consists of photodiodes that operate by converting light energy in the form of photons into an electronic charge. A charge is created when photons strike the semiconducting material.

Lixiviation is often followed by a Counter Current Decantation (CCD) circuit to recover the valuable mineral from the gangue. CCD consists of washing the feed slurry in a series of thickeners until the majority of the dissolved metals are removed. The conventional choice for this process has been high-rate thickeners.
The pulp at each step approaches the discharge end of the mill while the solution goes to the feed end—hence countercurrent decantation. Variables Affecting Decantation Process The principal variables that may affect the efficiency of the process are: Grade of ore. Ratio of solution precipitated to ore treated.
What does CCD mean in Technology? 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.

Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%.
Counter Current Decantation. Counter Current Washing and Leaching Calculations. Many processes in the hydrometallurgical and chemical industries require the separation of dissolved material from suspended solids. Counter current decantation (CCD) with thickeners is one of the methods generally used.

The solution is separated from the ore by methods such as filtration (e.g. vertical leaf type clarifier filters) and counter current decantation (CCD). Afterwards a very clear solution is achieved by using pre-coated filters applying diatomaceous earth. Oxygen is then removed by passing the solution through a vacuum de-aeration column.

The slurry is passed on to the CCD (counter current decantation), which is the sequence in which the material is fed from the leaching tank versus settling, in other words a solid liquid separating process. The solids which now contain very little uranium, settle at the bottom and are then pumped out to the tailings dam. ...
