Maximize Precious Metals Recovery With CCD Circuits And ...

High-rate thickeners are common for Counter Current Decantation (CCD) ... Maximize Precious Metals Recovery with CCD Circuits and High-Density Thickeners. Posted by Mick L. McCaslin, ... A single high-density or paste unit in a CCD circuit may also have advantages. For example, it may be economically viable to use high-rate thickeners in all ... Nickel and cobalt are precipitated from the solution leaving counter-current decantation as a mixed nickel–cobalt sulfide using hydrogen sulfide gas. The advantage of this precipitation is that many of the impurities in the solution do not co-precipitate.

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.
