counter current decantation thickener
Maximize Precious Metals Recovery with CCD Circuits and ...
Mar 28, 2017· 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 highrate thickeners.
