Counter Current Decantation Design Formula

Counter Current Decantation Applications The application of the Counter Current Decantation process is illustrated by the accompanying typical flow sheets. Figure 36 (type B) shows the most common type of flow sheet in use, where the ore settles readily to 50 per cent moisture or less, and where a strong cyanide solution is not required.
